Not all the bumps are Puss filled.. .but where they are it seems to be ummm yellowish white puss (like an infected pussy substance) and seems to be irritated around the hair folicles... so maybe the nervous reaction is causing the irritation to the hair follicles??

and if I poke around at the dry chapped like bumps on her heels the hair growing out of those areas can be pulled out like plucking feathers from a chicken...

my poor sweet puppy is being so good while we pick at her trying to figure out what's wrong...

now she has more bumps I just noticed going up her neck...

on her back and her neck.. they are sporadic like chicken pox? dogs don't get chicken pox do they?
