How long should it take for switching dog food to stop hair loss due to allergies? Other Pet Discussions
So my dog has lost a disturbing amount of hair. We took him to the vet and she said it looked like mange but the blood work came back negative. Then the vet said it was most likely an allergy to poultry. We switched to dog food with no poultry but it's been about two months and there is still no improvement. Should I wait longer to see improvement or insist that my vet send the blood work to be re-tested?
