Older Dog's Hypothyroidism

DEAR DR. FOX: My beloved 12-year-old purebred Siberian husky, Cassie, was sick off and on this year, but all the diagnostic tests and blood work we had done didn't show anything.

She lost her usual vim and vigor. She kept getting itches between her toes and on her belly that she licked and chewed on until she was raw and bloody, and she had occasional bouts of diarrhea. Finally, about six weeks ago, the latest round of blood work showed her thyroid levels have crashed -- off the charts, actually.

Cassie has been on the thyroid medicine for more than a month now, and she is doing well. All her health problems related to her drastically low thyroid levels have cleared up.

Unfortunately, she has an issue of shaking back legs, which is something else entirely. Now it has progressed to occasional full-body twitches and a general lack of good balance. Our vet and I suspect a neurological cause, but he says that even if we do a $3,000 MRI (which we would), often it does not show small tumors, so it's dubious whether to do it. And if we see a brain tumor, what then? We are not going to put her through that type of surgery at 12 years old.

She is happy, full of pep, totally enjoying her walks, has a good appetite and loves life, so we are just going to treasure every good day she has with us and see what happens. We don't know what else to do. This leg shaking and body twitching does not happen when she is walking or running, only when she stands still.

Have you personally experienced or know of any cases where a dog started off with mildly trembling back legs that progressed to full-on shaking, and then full-body twitches? Do you know what this might be? -- E.L., Holly, Mich.

DEAR E.L: I am glad you found that treatment for severe hypothyroidism, which can manifest in a variety of symptoms.

The spasms you describe are common in older dogs; the more severe shakes are linked most often with tumors or spinal deterioration from spondylosis. An MRI may or may not give the answer, and, as you said, then what? Regardless of the cost of making a possible diagnosis, there is probably no effective treatment that is not invasive or involving repeated chemotherapy or radiation, which may lower your dog's quality of life. If she is not in pain or fearful/anxious, I would try anti-inflammatory supplements, like good-quality fish oil; New Chapter's human Zyflamend supplement (give the same doses as for a human, with food, twice daily); Acetyl-L-carnitine; and massage therapy. Be sure she has a soft pad to rest on. In some instances, acupuncture and laser heat therapy can provide temporary relief.

My 15-year-old Indian pariah dog got some temporary relief from his spondylitis with prednisone. He was in pain and fear from this degenerative disease, which got worse and eventually lead to euthanasia.

DEAR DR. FOX: I've lived with cats all my life and thought I understood most of their behaviors, but there's one thing that my two cats do that has me stumped. Right as they begin to drink, they scratch the ground eight to 10 times right next to the bowl. They may take a drink or two as they do this, then they quit scratching and settle down in earnest to drink. I don't remember any of my other cats doing this. My two kitties are females, 11 and 13 years old.

Thanks for any insight you can give about this strange behavior. -- R.M., St. Louis

DEAR R.M.: My book, "Understanding Your Cat" (available now as an e-book at DrFoxVet.com), has helped thousands of people decipher feline behavior. Cats are copycats, and that explains why both your cats engage in a behavior you have never seen before. Being littermates makes them more likely to be copycats, and I advocate always adopting two littermates for the cats' sake -- they really need each other's company.

When cats paw around water and food bowls before drinking and eating I interpret it as a ritualistic, superstitious behavior, linked in the wild to uncovering and checking whatever they are going to ingest. Our two formerly feral cats routinely paw around their food bowls after eating and often cover them completely with the short throw rugs placed under their bowls.

Getting Rid of Eye Tear Stains

The Animal Doctor | May 20th, 2013

DEAR DR. FOX: We adopted our white standard poodle from a rescue shelter in 2003. We think she was about 2 years old at the time, so that would make her 12 years old now. She has been a very healthy dog all these years. However, in the past year, she has had a discharge from her eyes. The vet said that it was not uncommon in older dogs and even if he were to open the eye glands, the discharge would soon return. He suggested that we just use a warm washcloth with clear water to wipe off the eyes. We have been doing this and it does help to get rid of the crusty eye gunk, but I am wondering if there are any over-the-counter products that would help. We have to do this every day to keep up with it, and even then she looks like she has two black eyes all the time. We had a black standard poodle years ago, and he didn't seem to have this problem. Does it cause any infections or loss of eyesight? Do you have any other suggestions? -- S. and G.F., Collinsville, Ill.

DEAR S. and G.F.: Provided there are no in-curling eyelashes, blocked tear ducts or chronic conjunctivitis, which need special attention, simply clipping the long fur under the eyes and wiping daily with diluted boric acid or liquid vitamin C should suffice.

In many cases of staining tears and saliva, the culprit is a pigmented chemical called porphyrin, which animals secrete normally -- in gerbils it can look like dried blood in the corners of their eyes. Short-term antibiotic eye ointment may be needed if a bacterial infection is causing reddening of the conjunctiva, which may also produce staining porphyrins, possibly in conjunction with a fungal infection called malassezia. This is all too prevalent in dogs' ears. (Zymox Otic can provide effective relief for the ear.)

Oral treatment with a supplement such as Tearlax can help clear up dogs' eyes. Another oral supplement, Angel Eyes, contains the antibiotic tylosin, and I agree with other veterinarians who contend that this should not be given without strict veterinary oversight and should not be sold over the counter.

I have proposed that pet food dyes can also cause staining -- and more serious health problems -- and so one should seek pet foods without these artificial coloring agents.

STATES OF SHAME

What state do you live in? I live in Minnesota. Some of my taxes pay for legislators who put money before ethics and vested interests before animal rights and welfare. Recently, legislators pushed through a bill permitting the "sport" hunting and commercial trapping of wolves. This violates a five-year moratorium of such slaughter when the federal government took the wolf off the protected endangered species list. Shamefully, the Minnesota Agricultural Committee is currently blocking the Dog and Cat Breeder Regulation Bill, which passed through three House committees, because it sees the bill as a slippery slope to regulating how farmed animals are raised.

Comfort Before Death

The Animal Doctor by by Dr. Michael W. Fox
by Dr. Michael W. Fox
The Animal Doctor | May 19th, 2013

DEAR DR. FOX: Thank you so much for your answer to the reader who asked how animals feel about being euthanized. I read it the day before my 17-year-old cat Oliver died, and your vision of animals in an afterlife helped me through the next days.

I adopted Oliver from the Humane Society as an 8-month-old kitten as my husband was dealing with alcoholism. Oliver and my three other cats slept with me, keeping me warm and comforted through a very long winter. Oliver stoically accepted my new husband and his two brother cats with only a few disagreements. Oliver was the king of the household, and even in such a lively environment, the house seems strangely empty without him.

I knew he was dying when I read your column. The next day, he hid in the basement and I couldn't find him, though he called out a few times. When my husband and sons came home, they did a more careful search and found him. We brought him upstairs, put him on a soft blanket on a warm radiator. We all had a chance to pet him and talk to him before he died 15 minutes later. When my husband petted him, Oliver's back legs pumped a little and we told the boys he was already in another world chasing mice.

Thank you for letting me write about my cat. The day after he died, I talked to my pastor, who had recently lost his beloved dog, and we agreed that God certainly brings our animals into that "life after life" that you mentioned in your column. -- D.W., St. Louis

DEAR D.W.: Thanks for sharing your story about your beloved Oliver. Animals often go off to hide when they are close to dying. That is why it is important to keep an eye on dogs and cats who are terminally ill and might slip outdoors, since I have received a few letters from people whose aged animals have "disappeared," leaving the family to wonder about their fate and to have no real closure. It is a comfort to pets, I believe, to spend their last breath surrounded by their loved ones.

DEAR DR. FOX: I need some advice for my nearly 5-year-old cat. He is constantly scratching himself. He seems to be especially sensitive from about his mid-back to the base of his tail. He does not have fleas.

He is a somewhat large cat, so it is difficult for him to reach his lower back area. When he tries to do this, he loses his balance and tumbles over. He is also very insistent on someone petting him in this area. He will purr, mew, turn his head all around, and then he will start trying to bite at something on his leg. I've noticed that he's now managed to scratch a bald patch on his back.

We took him to the vet a couple of weeks ago, and he was diagnosed with dry skin. The vet had an oil product that could be placed on his food. My cat will not eat anything that is put into his food. How would you get a cat to consume something like this? The vet also recommended trying a humidifier.

He was given a steroid shot, which seemed to help for about a week. The vet did not think this problem was food-related. He eats Pro Plan Indoor Care Salmon and Rice. He is free fed and has five-eighths of a cup a day and never eats the entire bowl. I am not sure why he is so large.

Please advise. -- J.I., St Louis

DEAR J.L.: One of my cats had the same problem, and after considering hyperesthesia syndrome (hyperthyroidism and food allergy/intolerance), he greatly improved after I removed salmon from his diet. For other cats it could be corn, beef, dairy products, eggs or even rice -- you have to do some detective work.

Check the archives of my column on my website, DrFoxVet.com for more insights. Let me know the outcome.

DEAR DR. FOX: Our dog, Ellie, is an 11-year-old English setter rescue who we have had for about three years. About six months ago, she began to have fecal incontinence.

We have a doggy door and she goes in and out many times a day, but she seems to have no awareness that she is defecating. We took her to the vet and she was diagnosed as having arthritis of the spine.

Our vet said there isn't much that can be done for the incontinence, but said we could try giving her Proin (used for urinary incontinence) to see if it would help at all. This seemed to offer no relief, so we discontinued it. We have been giving her Pepto Bismol to make the stools firmer and easier to pick up, but that seems to not work any more. Do you have any other suggestions? Other than this problem, she is an active, happy girl. She survived a double mastectomy two years ago. -- J.C., Florissant, Mo.

DEAR J.C.: Old dogs do have this condition quite frequently, and it takes some patience and forbearance to be on the alert to get the dog outdoors in anticipation of the next evacuation.

Keeping the stools firm for easier indoor pick-up is best accomplished with 1 teaspoon of soaked psyllium husks (not the seeds) per 40 pounds of body weight every day, mixed in with the dog's regular food. Regular massage along the back and around the abdomen may also be helpful.

There are disposable doggy diapers that may make life easier for you and be quite comfortable for your old dog to wear.
