Has anyone ever given it to their Chi's? I had Roo into the vet briefly today to have sutures removed. Unrelated to that, she has come down with a case of hives on her head in the last couple of days so I had them look at it. She has allergies in general, but I'm wondering if it may be due to her dog food switch to Fromm, hope not as she loves it. I talked to my vet and they advised liquid Benadryl. I trust my vet, but I'm such a medicine phobe. Has anyone used liquid Benadryl for their chi?
