So effing mad!!! 😠😠😠😠

My husband and I have an 11 year old dog that struggles. He has a very hard time walking and getting up and down. He was my MIL's but she just left him here and my husband and I have taken very good care of him. She never took him to the vet or anything besides to get him fixed as a puppy. He has had to have almost all his teeth ripped out and 2 fatty tumors removed and more. I care about him and his health a lot. The vet said he is not allowed to have any more human food because he doesn't exercise enough, even with 2 walks a day. His arthritis just doesn't allow him to burn many calories. He is at a good weight now and stuff though. My MIL likes to feed him shit human food like pizza, tacos, enchiladas, even cinnamon toast crunch cereal!! I told her she cannot feed him stuff like this on her visit, but does she listen? No! She is going behind my back especially, but also in front of my face and giving him human food. It makes me so mad! She will be wanting to take him back at the end of next summer and I don't want her to take him! He will die miserable with her! He will get so fat that he won't be able to even get up off of the floor and then she will put him down! He has a couple more years left if she would keep him healthy and moving, but she won't! My poor boy!! 😞😢😭
