i have a 3 month old holland lop. I took him to the vet after I noticed he was having sneezing fits. Turns out he has a respiratory infection so he was prescribed enrofloxacin. It’s been 3 days and he has been barely moving. He doesn’t eat. He doesn’t use his litter or drink water. I had to give him a bath because he keeps peeing in the same area just sitting lethargic. I don’t know what to do. He is so stiff. He won’t even eat treats.
