Your pet recently had an intravenous mannitol injection for emergency treatment of glaucoma. There are several things that you should be aware of in order to best care for your pet.

This drug will make your pet urinate excessively. Although we give your dog the opportunity(s) to urinate after the injection, you should walk him or her again before leaving the hospital and frequently once you get home until its diuretic effects have dissipated.

Dogs are usually very thirsty after receiving this injection. But you do not want your dog to go home and gulp down a big bowl full of water. First of all, this can partially negate the effects of the injection. Second of all, that behavior could contribute to bloating, which is a dangerous condition.

Therefore, do not let your pet have any food or water for 3-4 hours after the injection. At that point, allow only small amounts of water at a time. So long as your dog has tolerated the re-introduction of water without any vomiting, you can give him or her some food.
