Good luck!
Wow, they must of come a long way with a cure for heartworm. Last year I only knew of 2 treatments, both were time consuming with multiple injections, days or weeks apart and months of quiet time for the dog. Then re-tests like every few months for a year or 2.

Thats great that all he needs is 2 shots, 2 days in a row.

Can't they re-test in 6 months?
