If your dog has asthma or another respiratory issue, prescription medication may be recommended by your veterinarian to help control their symptoms. Prescriptions for asthma medication and other respiratory medications for dogs can be filled at The Pharmacy at PetSmart; order online with a valid prescription from a vet. PetSmart knows how much you love your dog, so we carry medications that can help them breathe easier.
