Simparica Chewable Tablets for Dogs vs NexGard Chewable Flea Treatment for Dogs

Both are monthly beef-flavored chews that kill fleas and ticks, and both rate 4.7. Simparica starts killing fleas faster (about 3 hours vs about 4) and ticks within 8 hours, and it is labeled for dogs from 6 months and 2.8 lb. NexGard is labeled from 8 weeks and 4 lb, so it fits younger puppies, and it has a much larger review base. Pick Simparica for speed and a lower weight floor; pick NexGard for puppies under 6 months or if your dog needs a protein-free chew.

• Choose the Simparica if you want the fastest flea kill and a chew your dog can take from 2.8 lb and 6 months of age.
• Choose the NexGard if you have a puppy as young as 8 weeks or a dog with food sensitivities who needs a protein-free chew.
