WINTER WEATHER PROVIDES OPPORTUNITIES FOR OUTDOOR AND INDOOR FUN

With the Midwest and Eastern U.S. experiencing deep freezes this winter, plenty of dogs and their people will either be reveling in the snow or huddling by the fireplace trying to stay warm. Snow sports are a great way to take the edge off if you have an energetic dog who loves the outdoors, and you indoor types -- canine and human -- have options as well.

Of course, you and your dog can go for walks or hikes in the snow, but you might want to try snow-specific sports such as snowshoeing and skijoring. These activities are naturals for Nordic breeds, including Alaskan malamutes and Siberian huskies, but any athletic, conditioned dog can enjoy them.

Snowshoeing is as simple as strapping on a pair of snowshoes and striding out. Your dog doesn't need them; his paws are already equipped for traversing the snow.

Cross-country skiers with a need for speed may want to try skijoring: being pulled by one to three dogs. You'll need a skijoring belt or harness for yourself, a sled-dog harness for your dog, and an 8-foot or longer line to connect the two.

Any dog who loves to pull can skijor, but if he weighs less than 35 pounds, expect to provide most of the propulsion yourself.

Your dog will need to learn the commands "hike" (start), "haw" (left), "gee" (right), "on by" (ignore those squirrels) and "whoa" (no explanation necessary). Practice without skis first so you don't accidentally get pulled into a tree.

Places you can snowshoe or skijor include your neighborhood, golf courses, some wilderness areas or national and state park trails, or Nordic or snowshoe centers.

Avoid snowmobiling trails; there's too much risk of accidents when you're sharing the path with motorized vehicles. Know the rules wherever you're going and obey them. Dogs may be required to be on leash so they don't frighten or knock over others.

Does your dog need clothing in frigid weather? Veterinarian and canine sports medicine expert M. Christine Zink says a dog exercising continuously shouldn't need a coat because he creates his own heat. If your dog is out in the cold but not exerting a lot of energy, choose lightweight, stretchy items that don't restrict front-leg movement.

"Most that are non-stretchy restrict front-leg movement," Dr. Zink says. "That wastes energy and can even cause injuries if used a lot."

She also advises protecting a male dog's penis and testicles from the cold. You can find special coats made for field dogs that cover those vulnerable areas. He'll thank you for it.

Booties can be beneficial if your dog will be walking on salt-covered surfaces or has hairy feet that will collect ice balls, but only if they fit well, are comfortable and don't rub against the dog's paws. If your dog doesn't wear boots, soak his paws for a few seconds in a bowl of water to remove ice-melter chemicals.

Finally, be sure your dog has access to plenty of fresh water. He can quickly dehydrate in cold, dry weather.

Rather stay indoors with your dog? Take a handful of kibble or tiny treats, scatter it on the floor, and say "Find it." Some people feed whole meals this way. Play the muffin-tin game: Place a treat in each cup of a muffin tin and cover some of them with tennis balls or other dog toys. Then let your dog have at it. See how long it takes him to find the covered treats.

Whatever you do, be safe, have fun and snuggle often!

Q&A

Fur factors: Diet and

grooming improve coat

Q: My cat's coat is kind of dry and not very shiny. Is there any way I can improve it? What about supplements? -- via email

A: A cat's coat is more than a beautiful covering. It not only keeps the cat warm, it also helps to protect the skin from environmental or chemical damage. Healthy skin and hair offer better protection than dull, dry skin and hair. Hair also serves as an environmental sensor for cats, alerting them to heat or other threats.

If your cat's coat is rough, dull, dry or brittle, take her to the veterinarian. If he rules out ringworm or other health problems, the fault may lie in your cat's diet or grooming routine.

Cats are obligate carnivores, meaning they need high-quality protein and fat from meat. The body needs protein to produce hair and fat for shine and to improve absorption of fat-soluble vitamins. Whether you feed a canned or dry food, it should have a protein content ranging from 34 percent to 53 percent. Simply feeding a high-quality diet may be the only change you need to make to improve your cat's coat.

Can supplements make your cat's coat even better? If you are feeding a good food, supplements won't help and can even throw the diet out of whack if they're given in large amounts. It's more cost-effective to spend a little more on a high-quality diet than to try to supplement one that doesn't contain enough protein.

Supplements can be a good call if your cat has a disease that changes her ability to digest and absorb food or that requires her to eat a low-fat diet. Your veterinarian can recommend one that's right for your cat.

You can also improve your cat's coat from the outside by brushing and combing the fur to remove dirt and dead hairs. Specialized glands beneath the skin produce sebum, an oily substance that coats and waterproofs the hairs. Brushing distributes sebum and helps make the coat shiny. Weekly brushing is plenty for shorthaired cats. Depending on the breed, longhaired cats may need to be brushed a couple of times a week or daily. -- Dr. Marty Becker and Kim Campbell Thornton

The poop: Dogs sensitive

to Earth's magnetic field

-- We know that several animal species align their bodies to the Earth's magnetic field lines when performing certain behaviors such as grazing, hunting or migrating, but until now it wasn't known whether dogs did the same thing. In a two-year study published in Frontiers in Zoology, European researchers proved magnetic sensitivity in dogs by measuring the direction faced by 70 dogs of 37 different breeds when defecating or urinating and comparing the data to geomagnetic conditions at the time. Turns out that when the Earth's magnetic field is calm -- only about 20 percent of the daylight period -- dogs prefer to line up along the north-south axis.

-- Got dust? And dogs? Good news! Your child may have less risk of developing asthma and allergies. A new study suggests that exposure to dust from homes with dogs may change the immune response to allergens and other asthma triggers by affecting the makeup of the bugs that inhabit the gut: the microbiome. The findings, published in Proceedings of the National Academy of Sciences, show that dog-associated house dust can play a key role in preventing allergic inflammation. They help demonstrate how environmental exposures may protect against airway allergens and asthma.

-- An 85-pound black Labrador retriever named Bubba was killed recently at his home in Glendale, Calif., likely by a mountain lion. The big cats are capable of bringing down 150-pound deer and have been known to drag 100-pound deer into trees to dine on them at their leisure. Bubba was dragged over a 3 1/2-foot wall. To protect your pets from predators, don't leave pet food or water outdoors at night and keep pets indoors after dark. Motion-sensitive lights can also scare away the predators. -- Kim Campbell Thornton

WANT YOUR DOGS TO BE WELCOME WHEN YOU TRAVEL? PLAN AHEAD AND BE CONSIDERATE

By Kim Campbell Thornton

Many of us travel during the holidays to visit family or to experience the beauty of a celebration in a favorite place. We did both over the Christmas holiday, packing up the dogs for a road trip to Santa Fe, N.M., for the Yule festivities, followed by a visit with family in Magdalena.

Dogs are part of my family, but bringing them along requires a good bit of packing and preparation, not to mention higher than normal levels of supervision. Our 6-year-old cavalier, Harper, is an experienced traveler who took her first plane ride when she was just 6 months old, but senior dog Gemma and foster dog Kibo were unknown quantities as far as staying in hotels or other people's homes.

I'm happy to say that they acquitted themselves respectably during their stays in three different hotels, four different rooms, and visits to two different homes, including one with other dogs. There was a close call in a hotel hallway and in one of the homes, but a sharp eye and quick responses ensured that we didn't have any potty accidents to clean up along the way. From 20 years of traveling with dogs, here are my best tips on having a successful trip at any time of year.

-- Reserve a room early at a pet-friendly hotel, especially if you are visiting a tourist destination such as Santa Fe. The streets were crowded with visitors, and we weren't the only ones with dogs. Confirm that the room is pet-friendly a few weeks beforehand.

-- If you're driving to your destination, fill a gallon jug with water from home and mix it with the tap water at the places you visit. Even though the water is treated, different areas have different "bugs" in the system, and your dog will be less likely to have stomach upset from the change.

-- Some dogs suffer motion sickness. If yours is one of them, ask your veterinarian about Cerenia to prevent nausea and vomiting. Give it with a small amount of food half an hour to an hour before you hit the road.

-- Make feeding time easy, especially if you feed an unusual brand or a raw diet. Before you leave, contact pet-supply stores at your destination to make sure they carry your dog's food in case you run out. We pack dehydrated food and just add warm water.

-- Even the best-trained dog can have an accident in a strange place or get sick and vomit or suffer diarrhea. Bring along a bottle of odor and stain remover and towels for cleanup -- don't use the hotel's towels or the ones in your sister-in-law's bathroom!

-- A hard and fast rule for us is that all dogs must empty their bladders before setting paw in hotel or home. That's especially important if you're visiting a home (or hotel) where there are other dogs.

-- When visiting family, let the dogs meet outdoors before they all go inside. Gemma grouses in the presence of strange dogs, but once she has a few minutes to adjust -- and realize she's in their territory -- she settles down and becomes polite.

-- Take into account unusual conditions or places. Santa Fe's chilly winter climate was a shock to tiny Gemma, used to warmer California weather, but she stayed warm and cozy in a red fleece coat. At a crowded event, she rode in a tote bag, but otherwise she explored "The City Different" on her own four legs.

The best part of our trip? Being told that our dogs would be welcome back any time.

Q&A

Dialysis helps cats

recover kidney function

Q: I noticed that my cat was vomiting occasionally, and he was a little wobbly when he walked. Most worrisome, he turned up his nose at tuna. When I took him to the vet, they ran blood tests, which showed that his kidney function was abnormal because of an infection. Will dialysis help? -- via email

A: The kidneys are the body's waste removal system. They eliminate toxins from the body via the urine. When the kidneys aren't working, toxins build up, causing illness. As you discovered, an infection can prevent the kidneys from doing their job, but if they haven't been too severely damaged, dialysis can give the small, bean-shaped organs time to recuperate.

Dialysis performs the kidneys' job of waste removal until the kidneys can get back on the job. Cats who are very ill usually must be hospitalized for treatment and will receive either intermittent hemodialysis or continuous renal replacement therapy, both of which require machines with filters to remove and cleanse the blood.

Once the cat becomes more stable, the veterinarian may place what's called a peritoneal dialysis catheter, which allows the cat to stay at home between treatments. For peritoneal dialysis, expect to take your cat in for treatment three days a week. You may also need to give your cat oral antibiotics and administer fluids subcutaneously (beneath the skin) while the kidney infection is treated. It can take one to four weeks for the kidneys to heal completely.

According to the Animal Medical Center in New York City, damage caused by infections can be successfully treated 50 to 75 percent of the time. A kidney infection like the one your cat developed is a good example of how having pet health insurance can pay off.

Dialysis is expensive, especially if it requires hospitalization, but in the case of an infection, it gives the cat a chance to recover and lead a normal life. -- Dr. Marty Becker

Good food delivered

for people and pets

-- Seniors who receive food deliveries from Meals on Wheels have been known to share the meals with their beloved pets when nothing else is available, so the organization created WALOP (We All Love Our Pets), a national initiative to deliver pet food to clients who need help feeding their animals.

Since 2006, WALOP has focused on serving the relationship between people and pets, building a financial and nutritional safety net for them through donations, volunteers and help from shelters, other pet groups and organizations such as Banfield Charitable Trust, which provides grants to member programs.

-- Who doesn't love to look at pictures of dogs? When Elias Weiss Friedman realized that his photos of dogs were getting more attention than anything else he posted to Instagram, he created The Dogist, a blog dedicated to documenting the beauty of dogs. Now he pads the streets of New York City daily, looking for subjects. Friedman told The Huffington Post that his mission statement was "All the dogs," saying, "Every dog deserves recognition, and sometimes a compelling photograph can get a dog out of a shelter or inspire people to appreciate their dogs more."

-- According to a survey by website Rover.com, the most popular dog names of 2013 were Bella, Lucy, Bailey, Daisy, Lily, Molly, Lola, Maggie, Sadie and Chloe for females, and Max, Charlie, Buddy, Jack, Cooper, Rocky, Riley, Toby, Bear and Harley for males. The names frequently overlap with those given to children, cementing dogs' role as beloved family members.

PROPOSED FDA REGULATIONS WOULD ADDRESS PET FOOD SAFETY

By Kim Campbell Thornton

Nothing is certain in life except death and taxes and, increasingly, pet food and treat recalls. There were 33 in 2013. On average, that's one every 11 days. And between 2008 and 2012, the Food and Drug Administration received more than 2,500 complaints from consumers regarding pet food and livestock feed. The complaints ranged from an animal refusing to eat a food to illness and death associated with eating a particular food.

Food safety issues include microbial hazards -- primarily salmonella bacteria; physical hazards, such as glass, metal or plastic found in food; and nutrient imbalances, such as inadequate levels of thiamine in cat food. Toxic levels of animal drugs have also been found in non-medicated animal food, according to the FDA.

People can disagree about the nutritional merits of commercial pet foods, but the fact remains that if you buy pet food, you should be able to rely on its safety. The FDA, after years of prodding, has for the first time proposed regulations that, if passed, would oversee the manufacture of pet food and set standards to help prevent contamination. The focus is on preventing rather than responding to safety issues.

The proposal benefits people, too. They can acquire foodborne illnesses from handling contaminated pet food or touching pets who have eaten contaminated food.

Among the suggested changes: Manufacturers would be required to set out a written food safety plan, put in place controls for likely hazards, maintain certain standards of cleanliness, implement record-keeping provisions, and have a written plan for responding to outbreaks of foodborne illnesses. Inspectors will have more power to act before contaminated products reach store shelves and to restrict imports from suppliers who don't meet the new standards.

If the proposal passes, manufacturers will have one year from the date of publication of the final rule to meet the new requirements. Smaller businesses will have two to three years to comply.

Those are advances -- if they go into effect -- but because nothing is ever completely safe, pets can still be vulnerable to contaminated food. Here are steps you can take to reduce your dog's or cat's risk.

-- Mix it up. Don't feed the same brand or flavor all the time. If you rotate food frequently, your pet will be less likely to encounter a bad batch.

-- Call the manufacturer. Use the toll-free number on the bag or can to ask about ingredient quality, safety protocols and sourcing of ingredients. Often, ingredients are imported from other countries, including China or Egypt. Ask what measures the manufacturer takes to ensure that ingredients aren't contaminated. Does the manufacturer test finished products for pathogens before shipping them (known as "test and hold")?

-- Choose undamaged containers. The Centers for Disease Control recommends avoiding bags with visible signs of damage to the packaging, such as tears or discoloration, and cans with dents.

-- Photograph package codes and expiration dates so you have a record if there's a problem.

-- Scoop food out of the container using a clean measuring scoop, spoon or cup, not your pet's food bowl.

-- Wash pet food dishes in hot, soapy water after every meal or run them through the dishwasher. It will kill bacteria -- and besides, your pet doesn't want to eat out of a dirty dish any more than you do.

-- Report any adverse reactions to foods or treats to the FDA's Safety Reporting Portal at safetyreporting.hhs.gov.

Q&A

Rabbit dietary needs:

hay, yes; carrots, no

Q: We have a bunny in the classroom, and I want to make sure he is getting a proper diet. The kids love to give him carrots; is that all right? -- via Facebook

A: Peter Rabbit notwithstanding, carrots are not a good treat for rabbits, let alone a regular meal. They are high in sugar and can quickly upset a bunny tummy. Rabbits have interesting digestive tracts. They're not able to vomit, so if they eat something that's not good for them, it can really cause problems. It's not difficult to feed rabbits, but they do have distinct dietary needs.

Rabbits are herbivores, and they need to eat grasses such as hay or timothy every day. Other good additions to their diet include a cup per day of leafy greens, such as cilantro, dandelion greens, kale and red leaf lettuce.

Pelleted diets are available for rabbits, but they should be a supplement to the hay and greens, not the sole diet. Choose plain pellets, not those that resemble Lucky Charms cereal, and don't give more than one-quarter cup per day. It's easy to overfeed rabbits, but it's not good for them.

What about treats? It's very easy to give a rabbit too much sugar, which causes painful and messy diarrhea, so sweet foods such as fruit and carrots are best avoided. If you want to give some fruit, offer a small piece of organic apple peel or the top of a strawberry. Skip carrots, bananas, yogurt treats or other dairy foods, and anything that contains honey or seeds.

Remember that rabbits are much smaller than humans. When you give a treat, the portion size should be no larger than the joint end of your pinky finger. It's best to let one child each day offer the bunny a treat, instead of running the risk of overfeeding him and causing stomach upset. -- Kim Campbell Thornton and Dr. Marty Becker

Service dog aids doctors

during medical procedure

-- J.J. doesn't have an M.D. or even an R.N. after his name, but he was an essential part of the medical team recently at Duke University Medical Center when his charge, 7-year-old Kaelyn Krawczyk, underwent an anesthetic procedure. Kaelyn has a condition that can cause her to have mild to severe allergic reactions in response to even normal stimuli, such as heat or cold. J.J. is a service dog trained to detect the reactions before they occur. He alerted doctors twice during the recent procedure, allowing them to monitor Kaelyn more closely and take precautions to prevent a reaction.

-- Scientists at the USDA's Agricultural Research Service have developed a new way to make cat litter that's almost fully biodegradable -- using waste grains from corn ethanol production. Some cat litters are made with corn or other grains, but this is the first-known use of treated, spent grains, used primarily as an ingredient in cattle feed. The environmentally friendly litter made from dried distiller's grains was absorbent, formed strong clumps and provided good odor control.

-- What's the penalty for animal cruelty? In Kentucky, Iowa, South Dakota, New Mexico and Wyoming, the answer is, "Not much." Those states have the nation's weakest animal protection laws, according to a December 2013 report by the Animal Legal Defense Fund, which has tracked animal protection laws for eight years. The laws reflect inadequate standards of basic care, give limited authority to humane officers, and don't require mandatory reporting when veterinarians suspect animal cruelty. South Dakota is the only state with no felony penalty for acts of cruelty. The best states for animals? Laws in Illinois, Oregon, Michigan, Maine and California demonstrate a strong commitment to combating animal cruelty. -- Kim Campbell Thornton
