I have consulted my vet several times as my puppy always love to
scratch and these are what I was told to be the source of her
itch:
1. Things she eats/drinks/bites/chews (be it daily meals or
tibits-rewards),
2. Places she sleeps/plays,
3. Shampoo she uses,
4. Clothes (if any) she wears.
My puppy is on the verge of recovery as we have found item 1,3 to
be the source of her itch.
