Ok, Deuce always sheds a lot but this is different. He was on Ivermectin for Demodex mange, but after I ran out we decided we didn't want him on it anymore and so we haven't gotten a refill. He had a scab on his neck yesterday, but it was falling off and stuck in his hair. I started to get it out and like 10 hairs at a time would come out. I decided to check everywhere. I pinched a little bit of hair on his back and it pulled right out. I didn't pull hard at all and a lot came out. He is always scratching, and I thought it was from the mange, but they said it isn't supposed to itch. He doesn't have fleas either. Could this be an allergy to something like his food? He was on Royal Canin, but I just switched him this morning to DVP Duck and Potato since I saw his hair problem yesterday. It really freaked me out. I go to the vet tomorrow, so I will ask him, but I doubt he will be very helpful. He is nice and a good vet, but as you all know, they don't catch everything. Could this all be b/c of his food? If so I feel so bad for putting him on Ivermectin, who knows what that does to his insides. What do you guys think?
