I rescued a miniature bull terrier from my local humane society several months ago and have been trying desperatly to get Luke, my ig, used to the idea of having a dog around the house. Luke is used to being able to roam around the house whenever I am at home, but ever since Lucy, the dog, joined the family, i can't let him out to roam around. Lucy is fine with having an ig around, but Luke FREAKS OUT. he starts running into walls and going NUTS! I feel so bad making him stay in his cage all the time! I feel like a real jerk. The poor guy hasn't seen the sun in weeks. I need some helpfull advise, any would be greatly appreciated!!!!
