cowgirlc,
Don't be too quick to judge.
Having more than one of the best Bred dogs in the world, is not all that much of a problem. MANY here have multiple members of their Packs, and within those, sometimes there is a mix of Breeds.
For me, and, I have always thought, that when introducing a new member, it should be...
Same Breed, Opposite Sex, and the new animal younger then the Resident. I've always thought that maintaining the Seniority of the Resident animal, was very important.
My Female Becca, came to us as a Puppy, and My Male Sneakers accepted her with open Paws. He immediately took her as being HIS puppy, and it even got better from there.
Becca gets anything she wants, even Treats and Bones which Sneakers is chewing on, are relinquished should she show any interest in them. He has been her Teacher as well, and in ways that I could not have.
When Becca arrived, she was a shy little girl, who followed us and Sneakers around constantly. One thing that hasn't changed about her, is that her Tail wags constantly.
Sneakers is a very brave Dog, quite Territorial and Protective of our Pack, and is absolutely tireless, in his ability to monitor the house and property. One of his favorite places is, looking out an upstairs window, where he can see a large area, and, make sure that everyone knows there's something out there we should know about.
This is an activity he has taught Becca. And besides that, his habit of Pottying outside, his "secret" trails though the bushes, where the best scents of our local Possum and a couple of Cats that move through can be found. Becca now, is the first one out the door, to dispatch those Vicious Dangerous Squirrels back up in the Trees where they belong !
His help in raising Becca has been invaluable, which I suppose was the point of this Post to start with. Keep an open mind about that, having a second or more animals, that you really care about, can be very fulfilling.
