It’s could be a bone disease cuz when I lived at home my girl dog got ran over she was fine for a few months until she started showing signs of not eating or drinking anything then took her to the vet and she had some kind of bone disease I don’t remember what it was called tho
What’s rose is trying to say is u can’t just go up to a random person and be like hey u need to do this or u need to that it’s disrespectful let him deal with it
