Hello,
It really depends on many factors. Every dog is different. Some dogs get along well with everything, while others take longer. Your dogs personalities will decide how they get along. Consult a trainer in your area if you are having problems
Good luck

It could be an allergy or a skin condition Iike a pemphigus however, a vet needs to examine your dog to make a proper diagnosis.
Good Luck

Just as Dr. Dawn mentioned, it would be an allergy, reaction to fleas, something going on with her thyroid, etc. Or it could be mange. I was just reading up on sarcoptic mange since one of my boys is showing signs of this — and read that it is often one of the most difficult things to diagnose. And as a result, it is suspected that this condition is severely under diagnosed! This article recommended that if a dog is severely itchy, with no fleas present, then they should treat for sarcoptic mange. Then, if that does not solve the itch, only then start working on the assumption that it is an allergy.
So, if you don’t have a flea problem I would take her to a vet and discuss sarcoptic mange.
