Vet Q & AHow to buy Interceptor Plus for multiple dogs without a vet visit?
If you have proof that the dogs have a current negative heartworm test (current means a test within the last year) then you can get the product at any one of our VETCO vaccination clinics. If you do not have proof of a negative heartworm test, you can get the test done at the clinic and then you can buy the Interceptor (or any type of heartworm prevention).
