Frequently Asked Questions
How do I choose between Trifexis and Interceptor for spring heartworm prevention?
To choose the right product, compare the active ingredients and dosage forms; Trifexis combines milbemycin oxime with praziquantel for fleas, while Interceptor contains only milbemycin oxime. Consult your veterinarian to determine if your dog needs dual protection against fleas or just heartworms before selecting a specific brand.
Is it worth paying more for Trifexis compared to Interceptor?
Whether Trifexis is worth the higher price depends on whether your dog requires flea control in addition to heartworm prevention. If fleas are a concern, Trifexis offers combined protection, but if you use a separate flea treatment, Interceptor may be the more cost-effective option for heartworm prevention alone.
What is the best time of year to start spring heartworm prevention?
The best time to start prevention is as soon as local temperatures consistently rise above 57°F (14°C), which typically occurs in late March or early April depending on your region. Starting early ensures continuous protection before mosquitoes become active and transmit heartworm larvae.
How do I choose the correct dosage for my dog's Trifexis or Interceptor?
Select the chewable tablet size that matches your dog's weight range as indicated on the packaging, ensuring they are within the approved limits for each product. Always verify the specific weight bracket with your veterinarian to avoid under-dosing or overdosing your pet.
How do I administer Trifexis and Interceptor if my dog refuses chewables?
Both products are designed as chewable tablets that can be given whole, but you can hide them in a small amount of soft food like peanut butter or wet kibble if your dog resists. Ensure the food does not cover the tablet completely so the dog swallows it without chewing on the coating excessively.
What is the difference in price range between Trifexis and Interceptor?
Trifexis generally falls into a higher price range due to its dual-action formula protecting against both heartworms and fleas, whereas Interceptor is priced lower as it targets only heartworms. Budget-conscious owners might opt for Interceptor if they already manage flea control separately.
How do I know if my dog has been exposed to heartworms in the spring?
You cannot determine exposure just by symptoms, as heartworm disease often shows no signs until advanced stages; a simple blood test is required for diagnosis. Veterinarians recommend annual testing and year-round prevention rather than waiting for symptoms to appear after spring exposure.
