My mom has a 7 year old chihuahua that is on seizure medication so that limits the prescriptions for itching. She gets a bumps down the middle of her back and a rash on the inside of her legs and on her bottom. She'll scratch until she bleeds and she'll chew all her hair off if givin the chance. The vet says the only thing my mom can give her is childrens benedryl but that doesn't help. We have tried lotions, anti-itch otc, she gets a bath almost every day and doesn't have any fleas. We've tried giving her a bath twice a month but that doesn't help either. She eats kibbles and bits and whatever my mom eats during the day. I'm pretty sure if it was mange the vet would of said so. If you have any ideas or suggestions i'd really appreciate it. Thank you!
