Dogs and Puppies

Barbara asked:


Both dogs live together, and the bitch has been “locked” with the dog 3 times in last two days. The dogs belong to my son and he is proposing to neuter both dogs after one litter.

I have a 6 year old Boarder Collie bitch, she was once owned by a breader but had a large litter when she was about 18months. Due to a complication the breader had to have her spayed. So she was no good as a breeding dog thats how I managed to come bye her. The problem that she has is she can’t stand any small yapie dogs barking at her. She has a tendancy to first go into the stalk and then charge, she has nipped on a few ocasions but fortunatly for me the other owner presumed that it was their dog who was the agresser. Unfortunatly she is doing this more and more often and not with just small dogs now. On the hole she is a very smart dog and for the most time she is very obediant. Is there anything that i should be doing to stop this small spat of aggresion in my dog.
