our one year old vizsla rescue (we were told he's half GSP and we think he must have some grey hound too) started getting spots of missing hair on the back of his neck and upper back a couple weeks ago. It seems to be spreading but spotty. We got a biopsy done at vet a week ago but still have another week before we get results back. We've been giving this oil to put in his food and a foam to rub on his neck/back that the vet prescribed in meantime, but curious if anyone else experienced this. They looks scratchy and scaly. Pretty sure it's not ring worm because we would have had it by now. what are some common allergies you've seen with your dogs? We might start process of elimination.
