Canadavet.com has some good coupons and sales on heartworm medications. I got 2 years of Heartgard Plus there for $113 total. But there are less expensive choices even than Heartgard Plus. But I use it because it also has a dewormer and my yard has visitors– birds, deer, cats, squirrels, etc. Who knows what kind of worms might get tracked in??
