Why does he get on with every other puppy and a male adult dogs but not this puppy he's starting to show his teeth at this puppy he moves when she goes by him and doesnt want to know her could you please tell me will he ever get on with her or will he end up attacking her

Hi he may well get on with puppies away from his home and also male dogs but how many have actually been introduced to him on his home ground and then not gone away again? This new puppy is invading his space and he needs to be given time and support to accept the new member of the family. The pup should not be allowed to bother him unduly and he should be given plenty of posititive attention so that he doesnt feel pushed out.
