Not that I have seen any fleas, but I’m very concerned for her. She is a lab mix and I think she has some pit in her. She has been staying with my mom because I’ve been in the process of moving and my mom describes her as looking like she has mange. Can a dog lose her hair…literally chew it off because of nerves? I’m about to get her back after months so I will be taking her to the vet soon, but I’d like to do anything I can for her at home to make her comfortable first.

I brought my dog to the vet 4 weeks ago to try and figure out houw to fix my dogs chewing of her paws and tail region. He first advised to try Benadryl (a few months ago) and that didn’t help so we made an appointment. Since she isn’t too bad off (compared to other dogs and allergies) we decided to start with food trials. She has been eating Purina HA (hypoallergenic) formula for the last four weeks and I haven’t seen any sign of improvement.
Allergy testing is our next step, but I just want to make sure we are giving it the full amount of time to clear up if it a food allergy. Has anyone else gone through this with their dog? The vet said to try this for 6-8 weeks. Did it take that long for you to notice a difference? Or was it faster?
Just looking for previous experiences with this. Thanks!
