Why do adult dogs kill puppies? Is it because the puppy comes into the adult dog's territory so they kill them.
For many years I've handling my street dogs, one dog is my pet, it is always in my home, other 2 dogs are outsiders. These 2 outsider dogs always kill puppies.
Whenever my own pet's puppy or any other street dog puppy is near or around most of the dogs kill them. Similarly other dogs also kill other dog puppies.
Why don't adult dogs understand that the puppy is a child?
Just last week my puppy was killed by 2 street dogs. I was just going towards it but they killed in just 5 seconds. There was not any injuries on my puppy's body, Doctor told me that they both drilled it's lung, so it died in only 5 seconds. :(
As guided by Zaralynda , I have asked another question of "how to save them."
