what would cause a 5 month old puppy to bite nub of her tail raw. Sometimes she cries. Taking her to the vet tomorrow but what can i put on it to stop her from licking and biting it. Vet says it could be fleas but she has none, a food allergy, or if her anal sacs are full. There is no sign of smell coming from her rectum and its the nub that she's biting not the rectum. I've tried 1/2 dosage of childrens benedryl and also a tiny bit of cultivate steroid cream hoping to ease the itch. she has no fleas, she is on frontline, but was diagnosed and TREATED WITH MEDS FOR TWO WEEKS for tapeworm,roundworm and whipworm. I just need to know what i can put on her to stop the scratching as its so raw. Thank you.
Optional Information:
Female; Breed: cockapoo( 5 months 16 lbs).
Already Tried:
childrens liquid benedryl 1 teaspoon.
cultivate steroid cream (a tiny bit just on the nub)
