Release the hounds

For a while now, I have had my dog living inside my room, cuz we have a dog waiting to be adopted living with us as well and they always fight (ugly fight, bites that end up in blood and all) so they cant be together. I feel so bad for my dog, Im always afraid, what if something happens to him and he forgets what it was like to walk freely :(

Well, sometimes you wish having a second animal were simple, but dont forget about territories and stuff... This is why I only have one cat :/
