Hair Loss or Alopecia X
 
We have a yorkie who just turned 7 and she has very thin hair on her back. Her hair is normal everywhere else. Vet ran all kinds of test and said everything was normal and there was no medical problem. She said we could put her on Melatonin and that might help. She weighs 5 lbs. Has anyone used melatonin for there pet before, were there side effects and if I decided to use it, how much and how often do I give it?
Thanks

Was he checked for mites? The vet would have needed to do a skin scrapping and look under a microscope

Was she checked for Cushings? That would def be a possibility. Thyroid test? My Wylie has Atypical Cushings and hair loss was one of his most obvious symptoms. Testing for Cushings can be a long, tedious process -- but it's treatable...so it's worth looking at. Usually the very first test to run is the Cortisol-Creatinine urine test -- this test doesn't rule in Cushings, but it can rule it out and tell you whether you need to proceed w/ the next steps for testing. :)

They ran all the test and they came back normal, no medical problems.

Maybe you could check your vet bill to see exactly what tests were done. Some vets are not real familiar with the issues that the Yorkie can be prone to have. They may have missed something that someone here has had experience with.

This article talks about Alopecia X and Melatonin. Melatonin is known for establishing the inner clock. I would think living in Fl, with all the sun, you wouldn't have a problem. Also, this seems to work with breeds who shed and have winter and summer coats, Yorkie's aren't known for shedding.

If your dog is already neutered, or if neutering did not solve the problem, oral melatonin or melatonin implants may help. About one in three dogs are helped by it. Melatonin is a hormone produced in a small structure adjacent to the brain called the pineal body as well as in other areas of the body. It is important in establishing daily and seasonal rhythms in all creatures. Many dogs shed and re-grow their hair coat in a seasonal rhythm as wolves still do. This may be why some cases of Alopecia X respond well to melatonin supplements and might give us a hint as to the underlying problem in Nordic breeds. Some dogs begin to re-grow their hair within 1-3 month of beginning a melatonin supplement. A problem is that we do not know how to accurately determine the best dose, how frequently to give it or how long to give it. It does not appear that giving the standard 3 mg tablets is dangerous. But it some veterinarians think that giving too much melatonin or giving it over too long a period can actually make the problem worse. This could be an illusion in dogs that are not melatonin-responsive and would be loosing more hair in any case. My suggestion is to begin at a low dose and only increase the amount if no response is noted. Since this hormone is designed to pulse and not be continually supplied at a high levels, it is probably best not to continue giving it after the hair has returned. If the dog becomes sluggish or shows personality changes, the dose is probably too high. It should not be used in diabetic animals. Melatonin itself does not grow hair. But in some cases, it tricks the body into producing the compounds that do grow hair. Alopecia X
The ariticle also gives some other suggestions.
