Pets are quite prone to getting sick from infections that can be caused by parasites. Initially harmless, they can prove to be fatal to them in the long run. Especially if the pet is a dog. Every pet pharmacy recommends topical ointments and digestibles that can help your dog. However, some dogs completely disregard ointments and medicines because of the flavour and aftertaste. In this scenario, digestibles work best.

Almost every pet chemist online recommends NexGard and NexGard SPECTRA for dogs as it can be given as a chewable treat. But, what is the difference between the two? Let’s review.

What is NexGard?

Created by Merial, NexGard is a beef flavoured chewable for dogs. The purpose of this chewable treat is to kill bugs such as fleas and ticks with its medicinal content. These are the various types of ticks and bugs that get attracted to dogs and must be killed off at the earliest:

  • Black Legged Deer Tick
  • American Dog Tick
  • Lone Star Tick
  • Regular ticks
  • Fleas

What is NexGard SPECTRA?

In comparison, NexGard SPECTRA is an advanced version of its predecessor. Not to call NexGard less effective, both these types of chewable treats have their respective benefits.
