Blue buffalo was the only one I could find in my area and that was at the tractor supply store. They carry products for all farm animals and pets....He also told me I could buy what he sells but the names he gave me were just as good as what he sells...it is more expensive than most feed, but cheaper than buying it from him, even her wheezing when laying down has stopped...
I also turned to very good dog food to help my pup. I ended up with Taste of the Wild. Not cheap. And, likely not the solution to my poor boy’s allergies...since I see that the trend is his skin goes haywire at the end of summer, which is a high pollen/grass seed, etc. time in the Phx metro area. When the cold weather comes and the pollen is down, he goes back to normal. Still, I want a good food that I can trust...so Taste of the Wild is very good. I use whatever looks good/no byproducts/on sale at Petco for a topper. I’ve also been told by many that rawhide is pretty bad for dogs. It made my old bull terrier crazy with the paw licking until I removed ANY rawhide.
It’s all very frustrating. Hope your dog is doing better now...mine is...finally turning cool here.
