Dobey changing

Question
I have a 7 year old female Doberman that is not spayed and we have had her since she was 6 weeks old.  She is a great family dog and guard dog.  We added a female German Shorthair 4 years ago and she had a litter of pups 14 weeks ago.  We have sold all of the pups except one female we kept because when the mom delivered her and was cleaning her she bit one of her toes off so she only has 3 toes on one paw.  She is a love and really all 3 of the girls are great loveable dogs.  The problem we are having is the Doberman bit the puppie bad, and we had to take her to the vet to get medication.  The doberman is showing aggresive signs towards the puppie and I am not sure what to do other then keep them completely away from each other.  The mom of the pup does not even do anything about the Doberman messing with her pup either.  What can I do to make them get along, I want them to be family not only with us but each other?


Answer
Better leadership on your part might help. The key to most behavior problems is approaching things using the dog's natural instincts.  Dogs see all the people and dogs in the household as a pack with each having their own rank in the pack and a top dog.  Life is much easier if the 2 legged pack members outrank the 4 legged ones.  You can learn to play the role of top dog by reading some books or going to a good obedience class. A good obedience class or book is about you being top dog, not about rewarding standard commands with a treat.
