Where to buy cheaper heartworm and flea medicine?

Where can I find my heartworm and flea medicine cheaper than at the doctor?

Hmm, my last answer didn't show up. Maybe because I included links?

Okay, google the following companies. They seem to be consistently the cheapest:
"KV Vet"
"Revival Animal Health"
"Omaha Vaccine"

Many meds that are prescription for dogs are non-prescription for large animals. However, dogs and cows and horses get different doses of the active ingredient per pound (kilo) of body weight, so when using wormers, be very careful if you are trying to use large animal wormer on a dog. You can give too much and OD the dog, or too little, which will be ineffective.

Avoid any company that advertises on TV. In my experience they are always more costly than the animal vet supply houses that primarily market to vets, kennels and breeders.

Good luck, Pinky

try petmeds.com or healthypets.com.

I bought HeartGard and FrontLine Plus from this site:

It was the cheapest site I've found, and the products arrived fairly quickly to me, in California, USA, all in good order.

dollar store or family dollar store cost from 2.50 to 6.00
