This is an eight week old puppy, right? She is too young to have developed the antibodies that cause an allergic reaction. She is also too young to have left her mother. Yorkie puppies should stay with their mothers until they are twelve weeks old. She is too young to have had any vaccinations (or if she did they didn't take) so she is at a high risk for disease. She needs to be seen by a vet asap. |
