I had a Lhasa that developed some mysterious skin malady. He itched, chewed and scratched horribly. Very happy lovable dog otherwise. I tried everything, the omega 3, special foods, shampoos, treatments, screened for mites, fleas, mange everyhting was negative. He ended up losing almost all his hair and being stinky. I still loved him but he was not something pleasing to see. He would get skin infections all the time, was on steroids, it was terrible.
The ex said he ran away while I was deployed. I always was suspect. RIP Alex
