What is most effective for preventive heartworm treatment for a 100lb Rottweiller ? I understand there is a shot she can get that last 6 months. If so, what is it called and is it more effective than a monthly tab treatment ? If the monthly tab treatment is most effective or recommended, what is the best on the market to consider ? Also, what is the most effective Flea & Tick treatment on the market ? Thanks
Heartworm is all the same when it comes to it being effective. The shot is called Proheart. I like frontline plus for fleas and ticks. vetcare
