I hate my boyfriends dog.

I need some help. My boyfriend got a dog about six months ago, and I looooove puppies. But this dog is too much for me to handle. He freaks out every time someone walks in the door and will literally tear whatever clothes you’re wearing because he’s jumping on you so much. He knocks drinks off of tables because he won’t stop running around. You cannot close any door in the house because he will scratch on the door so much that he scratches the paint off. He steals food off the counter, chases the cat non stop, eats the furniture, and...HE IS NOT POTTY TRAINED. HE IS A 7 MONTH OLD BOXER/PITBULL MIX AND HE WILL NOT USE THE BATHROOM OUTSIDE. He will purposely hold it in until he gets back inside and then go. I am over this dog. Someone please give me some advice on this. He loves this dog so much. He ate my Kate Spade bag and my Uggs. I’m over it.
