Why cant i order heart worm pills on line directly from my vet? Cypress lakes animal hospital.

You need a prescription because if the dog has heart worms the preventative could kill him so the dr more or less has to sign off and say dog is healthy... If isnt on preventative already then dog will have to be tested before he can be on preventative...

I think you have to call them. I k ow they will give you a code to be able to buy them online
