I get it from my vet because you get 7 for the price of 6, and it's not much more expensive than Petmeds or wherever I used to get it. Also, my vet doest stuff like give my son's dogs rabies shots for free when I tell him the situation.

I have a country vet, whom I love. While you're waiting (they don't take appointments), you can hear horses whinnying and cows mooing, too.
