I am currently pet sitting a 6 yr. old maltese and after having him for just one night, I noticed he has several issues. He seems to have collapsed trachea from the way he breathes and him being overweight makes it even worst! She told me she free feeds and that I can adjust him onto my schedule since I don't free feed my babies. I also told her that I brush my babies' teeth every night so she can bring his toothbrush and I can brush his teeth too. Well, I noticed that the front row of his teeth is moving so he definitely needs extractions. His teeth are in poor condition with bad odor.
So, my problem is...how should I tell his owner when she returns? I really don't want her to be mad at me for telling her he has this and that issue. I also really don't want to be rude or offend her in any way. However, I really want him to get the care he needs. What would you guys suggest?? Also, I'm especially stuck on the overweight part. I am starting to feed him on a fixed schedule and walk him more so he should start to lose a little weight (he will be with me for a month and a half). If you were the owner, would you be mad if your dog lost weight?? I just really want to try and help him. I also don't know how to tell her he's overweight, I don't want to upset her. Btw, his knees are also not so good so I think losing weight would be good for him too. He's so chubby that you can barely feel his bones...
Thanks for reading and I look forward to some suggestions!
