okay i rent a room to my older sister. but she has a grandson that comes to stay the weedend. i have 3 dogs 1 male cocker spaniel mix and 1 dachshund chihuahua mix and 1whippet mix the whippet mix does not like him because everytime he came on the weekend he would tease her i told my sister that she needs to stop him from teasing her she said she would be never did. then we had a talk on what can we do to get her to stop trying to bite him i told her if she gets him to STOP teasing her then we well handle her to not bite him, i keep my word but she did not he kept teasing her so i told her that from now on if he visits he has to stay in her room because i'm not gonna lock my dogs in the room just so he can visit this is there house not his so she agree everything was going good until recently. she know she has to tell me or my wife to get the dog so he can leave she did that until oneday she took it upon herself to walk the kid out when my dog was not in the room we heard her barking so we went to see what she was barking at and it was my sister grandson i don't know what she plaining but i feel it not gonna be good she did it not once but 2 times so i don't want my dog to bite the kid and i don't want her to have my dog bite the kid so they could sue me if my dog bites him i told her the kid can't come in the house until we can get some paper work that gonna protect my house and my dog is there a contract i can download online and have her sign it if she agrees to the terms of the contract and should i get it notarize?
