Anaotilia, I'm aware that because of your location you don't have access to the type of vet care needed to help this little bunny. I will try and share what I can, but just be aware that
I am NOT a vet and I am only sharing what I have learned from my own experiences and research. Normally a rabbit in this condition needs
immediate vet care, but I understand you are doing the best you can to help this bunny without access to good vetcare.
Can you tell me what the hairloss is due to? Is if from urine soaked fur, diarrhea soaked fur, or both? If it is due to urine soaking the fur and the bunny is being kept in clean living conditions, then it is possible it has a urinary tract infection. In which case it would need the appropriate antibiotics to clear it up. If at all possible, it's best to have the urine tested to determine which bacteria is causing it and what antibiotic would work best, but I don't know if that is something you have available to you. I know that enrofloxacin is sometimes used for UTI's. Just make sure that the antibiotic used is safe for rabbits, as some can kill rabbits, and others if given by the wrong route can prove fatal. It is often helpful to give a rabbit probiotics when you are giving it antibiotics, to try and help keep it's gut flora in balance. It's best to use a non dairy probiotic if you have that available to you, as dairy based probiotics can sometimes cause digestive upset. You also want to give it at least an hour after giving the dose of antibiotics.

Is the bunny having watery diarrhea or mushy stools as well? Are you seeing any mucous in it? A swollen and distended belly is not a good sign. It's possible that this rabbit has an overgrowth of bad bacteria in the digestive tract or as ladysown mentioned, it could be coccidiosis. In which case, additional antibiotics or meds will need to be given. But along with that the diet that this bunny is on, needs to be changed. You need to stop the fruit, veggies, grains, and bread, and possibly the fresh grass too, if that is what you are giving. That is far to many sugars and carbs for a baby rabbit to be getting. Too many sugars and carbs in a rabbits diet, can upset the balance of digestive flora and cause an overgrowth of bad bacteria, which can lead to digestive problems and illness. And at it's young age, the veggies could be causing problems as well. Do you have access to dried grass hay or are you already feeding it? That is really the best thing to give a rabbit when it is having digestive problems, when the rabbit is still eating well on it's own. Is it still eating on it's own or are you having to syringe feed it? What are the pellets like that you are feeding?
