Help...my doodle has starting chewing and licking on her the inside of her paws until they are blood red. We thought it was possibly a food allergy so we changed her diet to not include chicken (chicken used to give her diarrhea as a puppy) So now she eats only high quality, no grain, dried food and either beef, lamb etc, but still to no avail. Apart from taking her to the vet for a steroid shot, I am completely baffled. We even stopped her from going out in into the garden for any length of time as we felt it was something either on the grass or in the soil...Please...any suggestions or idea????
