What are the key differences between Iverhart Max and Sentinel Spectrum?

One similarity between these two formulas is that they both contain Praziquantel as an active ingredient. Both products protect your dog against heartworms, hookworms, and roundworms.

Both of these medications are once-monthly, prescription-only treatments, and they both come in the form of a chewable tablet. Iverhart Max offers a beef and pork flavor, while Sentinel Spectrum boasts a beef flavor. Finally, both products are safe for use in puppies. Iverhart Max can be administered to puppies over 8 weeks old, and Sentinel Spectrum is safe for use in puppies over 6 weeks old weighing more than 2 pounds.

These formulas also have many distinguishing factors. In addition to Praziquantel, Iverhart Max contains Ivermectin and Pyrantel Pamoate. This product offers added protection against tapeworms. It is not proven safe for use in lactating, pregnant, or breeding dogs.

Sentinel Spectrum also contains three active ingredients. Along with Praziquantel, this formula uses Lufenuron and Milbemycin Oxime to protect against parasites. It works by stopping flea development. It also protects against whipworms.

Choosing between Iverhart Max and Sentinel Spectrum

If your primary goal is to protect your dog against dangerous parasites like heartworms, roundworms, and hookworms, you truly can’t go wrong with either of these amazing products. So, how do you decide between the two?! Your choice might come down to simple factors like your puppy’s age. If you have a puppy between 6 and 8 weeks old, Sentinel Spectrum is the safe choice. If your puppy is over 8 weeks old, you may choose either product (as long as the puppy weighs more than 2 pounds).

Your decision may rest upon the additional parasites you wish to protect your dog against. If you would prefer to focus on defending your pup against tapeworms, Iverhart Max is a great choice. If whipworms and fleas are more concerning for you and your pet, Sentinel Spectrum is a wonderful option.

Talk to your vet to determine whether or not one of these medications would work well for your dog. Your veterinarian will be able to answer all of your questions about these and any other parasite preventatives.
