Matisse would love to play with any dog that doesn't mind his in your face, no restraint kind of manners. If it's a big dog, he'll be careful of himself not to be hurt and will run circles around most big dogs. If it's a small dog, he'll wrestle and play tag. He loves to run and is can turn on a dime. So, those are games he's love to play along with things like tug of war.
Maurice is cheery and friendly too but may prefer to play in a little less boisterous way and would probably be best with a very small dog because he's just too tiny to mess with a bigger one. He's an ounce under 4 lbs.
Jose` is an old man and is not that over-the-top into too many other dogs. But he will make friends given a chance. And he is great friends with my son's dog. Of course, she lived with us for a couple years some time back. But strange dogs...hmmm, he might hit it off with one or two. He just can' play rough these days...getting a little arthritic.
