Mine are like 6 year old puppies. Questions?!?!
Just kidding! But, seriously, they still play with each other all the time, baiting each other, shoving toys into the other dog's face, then sprinting away, ambushing each other, or just boxing and wrestling with noisy growls from Purdy. I love it! (Although once in awhile, when I'm on the phone or watching a movie, it's a little much...)
They spend the rest of their time curled up together, arms and legs draped over each other.
I would suggest walking them, if you need some peace and quiet. That's probably the only way they'll both nap at the same time....and otherwise, learn to love it!
