In manitoba the vets,used to require the heartworm check before issuing a script now not needed. I usally buy mine with the rabies vac. Rev. is the best up here esp for the ticks, they literally fall off dead. I believe I pay around $110.00 for the green box large dog size. Not sure if a non customer could purchase, ie must have a dog on file in order to buy. But bloodwork not required.
