I have two German Sheppard Dogs from the same litter. One is long hair and he is the one that has the itching problem. I would hear him up all night scratching, chewing himself and such. I put him on Alegra once a day and that helped him from scratching his nose off. He is now 5 and has always been on a raw diet of ground duck, oats, coconut oil and vitamins. No people food whatsoever. His sister does not seem to have the same afflictions. I was given Apoquel a year ago by the vet, but read such horrible things about it, that i would not give it a try.
He eventually got worse with black skin, smells, skin infections and such itching, his quality of life was questionable. Something had to be done.
We tried Cytopoint about a month ago and so far it has bee a huge relief. He is a normal dog again. Long term, i will try to use it as little as possible. but right now, he has his coat back and chews on bones (natural and uncooked), instead of himself.
