Buying Guide

Confirm veterinary prescription

Many parasite and heartworm medications require a vet prescription and an annual exam to ensure safe use and correct dosing

Match active ingredients to needs

Choose based on active compounds—like afoxolaner, sarolaner, moxidectin or ivermectin—targeting fleas, ticks, heartworm, or intestinal worms as required

Consider dosing frequency

Monthly chewables versus 12-week formulations affect convenience and adherence; factor your routine when selecting a product

Dose by accurate weight

Select the tablet strength that matches your dog’s current weight range to ensure efficacy and reduce adverse reactions

Check broad-spectrum coverage

If multiple parasites are a concern, prefer combination formulations that protect against fleas, ticks, heartworm, and common intestinal worms

Assess flavor and administration

Chewable, palatable formulations can simplify monthly dosing, especially for small or picky dogs
