Our beagle, named Sassee, had heartworms and was tested clear just recently.

She had a mild case, it only required one overnight stay in hospital, another shot 2 weeks later, and 2 weeks after that the test to be sure she is clear.

The pill each month is what she will be doing. There is a shot that can be given covering 6 months, but some breeds can not handle the shot. Check with your vet if you would like to pursue the 6 month shot. We will be seeing if our Eli and Ginger can handle the shot.
