I have been going through a bit of an ordeal. My dog is having an allergic reaction to fleas. I think I have tried EVERYTHING to get rid of the fleas and nothing works. I feel so bad for him It is starting to effect his ears. Which it has never done before. I am going to the vet later today. The last time I went they put him on capstar, an antibiotic, and a steroid. The capstar helped temporarily. The antibiotic did get rid of the iritation. The steroid did nothing but make him drink a lot, hence constant urination. I have made the switch from Nutro to Canidea. I have also started putting fish oil in his food as well. I am so lost I really don't want to go back to the vet but I feel so bad for him. I hope this is the last time we have to go! Wish me luck!
