Pam,

If your pup keeps scratching check to see
if you can see anything on her skin such
as little bumps, or even dandruf etc.
If she continues to scratch you might
want your vet to do a skin scrapping.
I remember when we brought
our Norwich pup home
she was scratching. I noticed
I was scratching too.
I took the pup to the vet and he did
a skin scraping. She
had some type of mite(mange)that is common
with pups.

Could be anything such as allergy, dermatitis just a number
of things. Hopefully your pup is
no longer scratching by the time I
post this.
