I have 2 boys from the same liter! They are inseperable! I love having 2! Their personalities are soooo different and I feel that they need each other. I do work full time though so I feel sooo much better that when Im at work they have each other to play with! And honestly going through the puppy stage just once with them both would be much easier than going through the puppy stage again!
Go for it!!! You gotta train one anyways, you might as well train two, if you can afford the expense of 2!
