He is allergic to advantage gel...the anti flea stuff.  My poor Bernie has a bleeding rash.  OUCH!!!

Oh no!! Is he doing okay now? What did the vet say?

Wow, I'd never have thought about that kind of issue. We're about to start Tesla on hers after we give her a bath. :( Hope Bernie starts to heal soon!

Oh, poor Bernie!  I had a dog when I was little who was allergic to his flea treatment so I know what you are going through.  My dog was just miserable!  I hope he is feeling better soon and the rash heals quickly!
