Thinking about adding another Yorkie to the Family next year. But Worried....
 

I really want to get a girl Yorkie. I am thinking of getting one late next year from the same breeder I got Biggie from. I would prefer to get one from the same Mom as Biggie.
I realize 2 dogs will be more work, but what really concerns me is how my Biggie will be affected by a new addition. My husband doesn't think Biggie will do well with another dog. Biggie doesn't really seem to be into other dogs at the dog park. He goes up and smells them but he is more interested in smelling everything at the park rather than playing with other dogs. My brother in law has a german mix named Lucky. Lucky just turned 1. Biggie and Lucky get along for the most part, but Lucky tends to be rough and likes to lightly grab Biggie's legs and face..I know Lucky is just trying to play. Biggie goes nuts on Lucky and starts snarling..and then they get into a fight. I don't blame Biggie..he obviously doesn't like the rough playing. Biggie is also very territorial. He'll snap at Lucky if Lucky wants to sit on my lap..yes that big dog loves to sit on people's lap. :)
My concern is if we bring another dog that Biggie will be unhappy. He obviously will have to share our attention and affection. The last thing I want to do is make him miserable. I also don't want to fall in love with another dog to then have to give it up because Biggie is unhappy.
Is there any way to know if it is a good idea to bring another dog into the home or not?

I would suggest when you get closer to selecting a pup from the litter you take Biggie to see how he interacts with the pup. Overall I suggest getting a girl so there are no alpha issues. Also by taking him there he will be able to help pick that pup. You will be able to see how they interact. Then you can select a pup and maybe before bringing the new pup home go back for a couple more visits so they will really know each other when the time comes to go home with the new pup.

Good luck.

Whenever I bring a new one home, the oldest dog I have(almost 11) wants to start playing with them right away, then after that, she plays only when she wants to play, it usually takes the 6 year old and 3 1/2 year old about 2 weeks, then, they realize they're here to stay and they all start playing..I love having 4 of them in here..Just borrowing a dog won't prove anything..They have to know the "dog" is here to stay

Thanks to both of you for the replies.
