I would seriously consider going to the vet or at least calling one for an opinion re: the behavior you have witnessed etc. It would be very hard for any of us (and irresponsible) to make any assumptions about why your puppy isn't eating etc.
On one hand, the puppy may just be nervous due to age. On the other hand, something may be wrong since dogs do not show pain, distress etc in the same way as humans. It would be best for all concerned to get a professional opinion. |
