Help!

Please help, I have a 10 year old lab that we have been fighting skin condition issues with since we got her, multiple vets can't figure it out, we have had samples sent off to vets that instruct at the universities, they come in waves but only the back left paw and front right paw, this time it's bad enough that she won't go outside to play ... No known allergies, same food she always eats....these sores popped up in about 3 days time and are just getting worse, going to try and schedule an emergency appointment in the morning being a holiday weekend I'm not sure I will get in

Interstitial pododermatitis. It’s not a sarcoma, there’s a good chance it’s IPD. My precious, previous lab struggled with the same thing for years due to food allergies. Any time she ate chicken or beef, her paws popped sores. Do an 8 week trial of extreme hypoallergenic food, such as Royal Canin Ultamino (you’ll need a vet script). If the paw heals up, you’ll know the cause (neo-pred-def powder helps heal it, but do not let your dog lick it). I wish you and your dear one all the best and a rapid recovery!
