Sentinel Spectrum vs. Trifexis

Comparison between Sentinel Spectrum and Trifexis

Protecting your dog from heartworm and dangerous parasites can be fuss-free and simple by using a chewable or tablet.

Sentinel Spectrum and Trifexis prevent heartworm, hookworms, whipworm, and roundworms. In addition, sentinel Spectrum protects your dogs from tapeworms and may stop flea eggs from hatching. Trifexis has an additional advantage by killing adult fleas, larvae, and eggs.

As a dog parent, you must know that these treatments prevent heartworm development. Still, it does not treat existing heartworm, and your dog needs to be tested before administering medication.

Sentinel Spectrum is safe for puppies and dogs at the age of six weeks and has a minimum body weight of 2 lbs (0.9 kg). Trifexis is safe for puppies and dogs at eight weeks and has a minimum weight of 5 lbs (2.3 kg).

If the pet gets heartworm, it can be tough to treat, so prevention is better than cure. Here is our comparison of the leading brand of heartworm preventatives.
