Our puppy (who hasn't come home with us yet-still with her mommy and siblings) is very itchy. We took her to the vet and she has no allergies or fleas. I paid to take her there to get NO answers. I tried special shampoo from the vet, puppy calming meds, and nothing has worked. Then we tried putting a little Vaseline behind her ears and on her hind legs (that's where she's itching and biting) and it worked! She calmed down and hasn't itched since. She isn't licking it off either. Is this safe to use? Has anyone heard of this before? She's only 4.5 weeks old. Also, she's not from a breeder, she's from my BF's sister. Her two Cocker Spaniel's had puppies. His sister wants us to take her at 6 weeks but I think we should wait until she's 8 weeks. What do you think?
