Sorry that little Max doesn't want to eat. I know it can make you worried because we are usually so used to dogs loving to eat. So we know that they really don't feel good when they won't eat. Valentina was very picky about eating at first. She had to stay at the vet for 5 days after surgery and the vet actually brought in some turkey from home to try to get her to eat. She did end up eating bits of this and that at the vet and even after 5 days in the hospital she was still somewhat reluctant to eat. She was so focused on eating normally so I found this upsetting but I did read it was normal for the first few days or even a week or so post op. I found that she would eat if I hand fed her but if I gave it to her out of a bowl she would just turn her nose up at it. She did eat eggs and ground chicken out of my hand for the first few days after being home and then she started to get her appetite back. Even then though she still ate way less than normal but I tried to be patient and she slowly started eating more each day. Now she is eating close to her normal pre surgery amount. I am feeding her a little less because the vet said to be careful about her getting fat. She does alot of laying around so I don't think her calorie requirement is the same as before. Trying the catfood does seem like it may work. I had to use catfood in a pinch for my dogs before and they were crazy for it. It sounds like you are trying really hard and you are doing the right things. Just keep on trying different things and I really do think in a couple more days Max will start to eat. Giving him liquids through the syringe is a good idea. I do remember Valentina turning her head away from the water bowl at first and she was usually such a thirsty dog she would never turn down water.Interesting thing was I would give her ice and she would eat that. She has always loved to eat ice. I don't know if you can give Max ice or not because he is so small. I guess you could crush it up. I wonder also if it is ok to give dogs milk. I have never heard of giving dogs milk but it does have calories and some sugars and protein and it is a liquid so it will hydrate. You could ask your vet about that. Hope you find someway to get something significant in him. It will get better! Everyone has their own individual set of trials throughout the healing process and it is frustrating and tiring but it does get better. Just keep telling yourself that. That's what I had to do. Sorry you accidentally got bitten. It must be hard to give the meds if he won't eat. Sometimes I give Val's meds in food and sometimes I just go ahead and shove  em down her throat. But I really hate doing that. It feels so mean and intrusive. She was onto me about hiding it in foods and I was running out of things to hide it in. Also some of the things I was trying to hide it in were giving her digestive problems. Hope things get better for you and Max soon. Keep up the good work!!
