Buddy getting bald on one side again went to the vet have him on Benadryl and a spray from the vets. To me seems like it is spreading it is only on his right side ? the left side of the dog does not have hair loss the vet does not understand that nor do I. Buddy gets fed Canidae,or Taste of the Wild he also gets Salmon Oil capsules from Wal Mart ? also have been giving him Sardines in water. Any other ideas ?Thanks ahead of time he was like this last summer but this year is worse.He spends most of his time inside under the AC since it is very hot in Tulsa.
