Heartworm Disease can be a serious illness for dogs if left untreated. If you suspect your dog may have heartworm disease, make an appointment with your vet as soon as possible. After a visit to the vet has revealed that your dog has, in fact, contracted heartworm disease, your vet may write a prescription for heartworm medications for dogs. The Pharmacy at PetSmart is your go-to for filling prescriptions and carrying out veterinarian treatment plans. 
Pet parents on the search for heartworm medication should consult a vet before implementing any sort of new medication into their pet’s medical regimen. 
PetSmart customers can place prescription orders through The Pharmacy website, as long as they are active prescriptions that have been prescribed by a vet in the last 12 months.
Prescriptions from a licensed veterinarian are required to purchase Heartworm Medication from The Pharmacy at PetSmart. Need to find a vet? We have you covered.
