My Ruger will be 2 years old next month. He is one very spoiled Yorkie. He is such a mamas boy. We have a very good routine around our house. We have a time set for everything Ruger & I do. From going to bed @ the same time, getting up @ the same time. Eating, outside walks & potty time. He knows exactly when to go into his "tent" when I have to leave the house.
My concern is: I have an opportunity to get a male puppy. Now Ruger does like other dogs. We babysit another Yorkie every now and then, but this one is 9 years and doesn't want to play with Ruger.
What to do. I love him with all my heart. Afraid I'll turn his world up side down.
I would love to have him a brother. I'm also being selfish. I lost my 1st Yorkie @ 7 years old. If something bad happens to one I would still have a baby.
Help with advice please.
