I have two and I'm so glad I do. Joy is 5 and Jig is 1 and a half. They play together a lot and it is so cute. Joy is quiet and occasionally nervous by nature. When she doesn't want to play, Jig plays with us because he is very playful and has lots of energy. Both sleep with us. Both greet us at the door when we arrive home for the day. It warms my heart when they jump on their hind legs and wag their little tails so fast you can barely see them. They're both house trained. Jig was a little more difficult because he wanted to lift his leg on the furniture.
Jig went through a spell not too long ago where he wanted to get frisky with Joy, but it was short lived and we just put them in their separate kennels (they are also kennel trained) to keep Jig from wearing himself out.
