hi i recently got a dog and ive had her since the end of april her name is sholoh and when she gets nerveous she scratches and bites and now her end half is pretty much completly bald whats hapening?

Has she been treated for fleas Sweetie?

Warm regards Susan

we give her advantage every 6 weeks but i don't think its working susan

Does she have any other problems such as lethargy, being overweight?

no shes really active constantly being taken for walk or put through her agility course and shes 50 pounds the vet says she might even be underweight last time we went (2 months ago)
