Keeping your pet healthy and happy is one of your most important roles as a pet owner. Choosing a heartworm and parasite preventative for your pet can be tough because of the broad selection of products available. Two of the top treatment options are Interceptor and Sentinel Spectrum. These products are both incredibly effective, but they also differ in a number of ways. We’ve put together a table and some additional information to help you make an informed decision!

How does Interceptor differ from Sentinel Spectrum?
First, let’s discuss the similarities between these two top-of-the-line products. Both of these medications are chewable, once-monthly, beef-flavored tablets. They both contain Milbemycin Oxime as an active ingredient, which offers protection against roundworms, whipworms, and hookworms and works as a heartworm preventative.
Both products are safe for use in breeding or pregnant dogs, and they are both safe for puppies over 2 pounds as well - Interceptor can be administered to puppies from an age of 4 weeks, while Sentinel Spectrum can be administered to puppies 6 weeks old and up.
Now, it’s time to dive into the differences between Interceptor and Sentinel Spectrum. Firstly, Interceptor is safe for use in cats or nursing mother dogs, but Sentinel Spectrum is not formulated for feline use and has not been proven safe for use in lactating dogs. Sentinel Spectrum contains two additional active ingredients (Praziquantel and Lufenuron) for added protection against tapeworms and developing flea larvae and eggs.
Final thoughts on Interceptor vs. Sentinel Spectrum
Now that we’ve weighed the similarities and differences between these two treatment options, there are a couple of key ways to determine which product is best for your pet. These include:
- Will you be treating a cat, a puppy between the ages of 4 and 6 weeks, or a lactating dog? If so, Interceptor is the safest choice for your pet.
- Are you interested in a product that protects against developing fleas and against tapeworms? If so, you may want to choose Sentinel Spectrum.
Armed with this knowledge, it’s time to make an appointment with your veterinarian. Your vet knows you and your pet best, so he or she can confirm whether or not the treatment you’ve chosen is the best one for your specific pet. Your veterinarian will also be able to answer any questions you may have about these medications.
