I took Raja to meet my parent's dog, Izzy, yesterday (80 lb shepard mix) and he had a blast! Izzy was really delicate and careful with him, but there's still not much they could do together, other than Raja chasing her tail and trying to reach her face. My two cats mostly walk away when he starts playing with them, so I want to make him a few friends in our area.
I live in Hyattsville, about 5 minutes away from DC. There's a nice park down the street (Magruder) and we go to DC often, but I wouldn't mind having guests over to my home. Let us know if you want to play!
