MIL is coming....

My MIL will be here to stay with my husband and I on the 19th. A little bit of background so you understand fully.

2 years ago she left his father because of his drinking. We live in Utah and she moved all the way to Oklahoma. Then last year, his dad passed away. Their home they had together was empty and she needed/wanted it to be lived in so she asked us to move into it. She didn't ask us for rent, just to pay for our own bills and help with property tax and stuff which we were happy to do.

When she left though she left us the family dog. Didn't ask, just did it. Now, he is a good boy! A very good boy! He had not been taken care of well at all. He went from living with her, being extremely obese. His teeth weren't taken care of or anything. Then when he lived with my FIL he would forget to water and feed him so he got really thin and stuff.

My husband and I made sure that all changed. We got his teeth fixed which was expensive as hell by the way. He is a healthy weight, gets exercise, and has had new training to convenience him and us. He likes to lay in the middle of the walk way and if you try to pass him, he bites you same if you try to step over him. We have trained him to mostly lay on his orthopedic dog bed we got him so we don't hurt him and so we don't get bitten. He also is not allowed human food anymore because since he is old he puts weighg on very quickly. He also has a hard time walking because of age, so we don't want to make it harder for him to walk because of weight. He also isn't allowed in certain rooms anymore because they are areas I don't want him and my other dog getting into trouble in or getting hair all over.

My dilemma now will be that when she comes, she likes to break all of those rules even when I tell her them and their importance. She simply doesn't care and does whatever she wants. I will even tell her no and she ignores me. I know it's her home and technically her dog, but after she leaves I will have to put all the work back into him that we have worked so hard for! This happened last time and he gained weight and wouldn't listen to me when he got for weeks because he thought he no longer had to. I just hate having to go through it all over again because of her. It's so annoying.
