I've got a sick Hamburg. She's been like this for almost two weeks now, but she doesn't move much from the spot she is in, and she would eat when I'd offer it, but never by herself, same with water. She stays alert though, watching me with her eyes, moving her head. While outside she would puff up with her tail down when standing. I moved her inside last night, she drank a little bit of water last night and no food, so I made an almost completely watery mess of her food and she ate some of that this morning. It wasn't much, but it reassured me a little bit. Checking today she isn't puffed up, so I think I solved one problem of being cold. I've done all sorts of research and I just can't come up with anything solid. There are so many diseases out there with the same symptoms. I don't know what else I can do, or what I should. Does anyone have any tips?
