I have a rescue 4yo springer/beagle.. who scratches and bites his the tops of his legs.. vet claims it might be a skin irritation caused by food.. i had him on Acana wild prairie which is grain free - but now have been given hills prescription diet d/d which he doesnt like so much. He has also been taken off the marrobone treats from pedigree chum. We have omega 3 added to the diet and still things are the same with him.. any ideas would be great. Also any tips on how to get him to eat dry food, he eats once there are bits of ham or chicken hidden within the food, but otherwise he doesnt. Any neat tips would be great. any beagle/springer owners out there.. i think he is that, is there a place i can send away to be sure?
