Confinement

To do or not to do? Well, it depends on the severity of the case, preference/assessment of the veterinarian and budget/cost of the treatment. It is necessary to monitor the pet's health for the next 24-48 hours especially during emergency situations like hit-by-car or poisonings. It would require restricted area for movement which is important for fractures, intravenous fluids to stabilize patient and antibiotics/supplements infusion to treat underlying diseases. However, because of financial constraints, owners may refuse this recommendation. If so, I think it is prerogative for the vet to give first aid, prescription and alternatives to consider the pet's condition.
