I have 7 6 week old pups. This morning the runt of the liter was attacked by one of the other pups multiple times. She isn't injured. Now the other pups are trying to attack the runt. Is there a possible reason as to why the pups would be trying to attack the runt?
If your puppy is the smallest,it can be normal the rest of puppies want to eliminate.It is a normal behaviour between the puppies.
You should separate it physically of the rest of the puppies and then,it will be able to eat more and it will grow up quiker than now.
