Buying Guide

Know the target parasites

Choose products labeled for the specific parasites you need to control—flea/tick-only agents differ from heartworm preventives or multi-parasite treatments

Match dose to your dog

Select the tablet or chewable strength that corresponds to your dog’s weight class to ensure proper dosing and safety

Prefer combination protection when needed

If you need both heartworm prevention and flea/tick control, consider combination chewables that cover multiple parasites in one monthly dose

Check formulation and palatability

Oral chewables in flavors like beef make dosing easier for many dogs; confirm your dog will accept the formulation offered

Factor recurring cost

Estimate monthly or annual cost based on per-dose price and dosing frequency to compare value across options under $200
