One chew every three months — the longest gap between doses in this lineup.

BRAVECTO is the choice for owners who want to set a reminder and forget about monthly dosing. This single pork-flavored chew gives your dog up to 12 weeks of protection from fleas and ticks (the label says “up to 12 weeks” per chew), while the monthly products here are dosed monthly. Owners mention that it is “highly effective flea treatment; eliminated all fleas quickly, dog comfortable and happy,” and one reviewer noted their dog needed to have it chopped into food because younger dogs disliked the taste. Unlike the Credelio or Simparica Trio below, BRAVECTO does not cover heartworm or intestinal worms — it is purely a flea-and-tick product. The trade-off for that long convenience is that you need a separate heartworm preventive if your vet recommends one.

The dosing directions require that you give it with food to help the medication absorb properly. Several long-term users reported six years of use across multiple dogs with no side effects, just “beautiful coats and happy dogs.” One honest buyer noted an initial vomiting reaction only when the chew was combined with a topical treatment — given alone, the dog had no further issues.

Seven types of parasites in one chewable — the broadest coverage of any product on this list.

Credelio Quattro covers more than any other chewable here: ticks, fleas, heartworm disease, New World screwworm larvae, and three intestinal worms (roundworms, hookworms, tapeworms) that can be passed to humans. That broad spectrum makes it a strong pick for owners who want a single tablet to handle multiple threats. At 12.1-25 lbs, this size is for smaller dogs, while the Simparica Trio version below is for 44.1-88 lbs, so check your dog’s weight carefully. The chew begins killing ticks and fleas within 4 hours, and the manufacturer reports successful administration to 98% of dogs in a U.S. field study. One buyer reports “My dog loves this, they are easily tolerable and she eats it like candy.”

The package contains just one chewable tablet (a single monthly dose), so you will need to reorder each month. The 1.6-ounce item weight matches the NexGard 6-count pack but delivers far more parasite types per chew. A few reviewers noted it was veterinarian-recommended and that the product “works great,” though one buyer mentioned needing to use it a little longer to be completely sure about effectiveness. Unlike Simparica Trio, which protects against heartworm but also six types of ticks, Credelio Quattro’s tick coverage is broad but its real strength is the number of parasite types overall.

A monthly chew that covers heartworm, six types of ticks, fleas, and two intestinal worms in one tablet.

Simparica Trio is the triple-threat option: it prevents heartworm disease, kills six types of ticks (including Deer Tick and Lone Star Tick), kills fleas before they lay eggs, and treats roundworms and hookworms. It is approved for puppies as young as eight weeks old and at least 2.8 lbs, though this specific size is for dogs weighing 44.1-88 lbs. The chewable is colored green and weighs 1.6 ounces. Shoppers say “Dog likes taste, takes easily” and that tablets can be broken up and mixed with food — one reviewer did this with no issue. A few owners mentioned minor initial stomach upset that resolved quickly, which is a common note for monthly parasite preventives.

This product is the first combo preventative FDA-approved to kill six types of ticks, and it is also approved to prevent Lyme infections from black-legged ticks. It comes with a 100% satisfaction guarantee from the manufacturer. The monthly dosing schedule is straightforward, and the subscription option on Amazon makes automatic refills easy. Unlike Credelio Quattro, Simparica Trio does not cover tapeworms, but its heartworm and tick coverage is very strong. One owner reported it is “better than the liquid that you put on the back of their necks,” referring to topical treatments that can irritate skin.

Six months of flea and tick protection in one box, with a beef flavor dogs actually love.

NexGard is the #1 vet-recommended flea and tick chewable, and this 6-count package covers half a year of monthly doses. It kills fleas before they can lay eggs and prevents Lyme infections by killing black-legged ticks. The beef flavor is a real differentiator: the manufacturer says it is “#1-preferred by dogs,” and buyers confirm it — one reviewer with years of use reports “Effective flea/tick prevention for dogs; no infestations in years of use.” At 1.6 ounces for the pack of 6 chews, the individual chews are small enough that most dogs take them without fuss. This size is for dogs 24.1-60 lbs, which covers a wide middle range of breeds.

The main drawback is clear in the reviews: the price. One buyer gave it 4 stars only because of the “high price,” noting they would give 5 stars if it cost less. NexGard covers fleas and ticks but not heartworm or intestinal worms, so you will need a separate heartworm preventive. The dosing is once a month, and you can give it with or without food. Unlike BRAVECTO, which is a 12-week chew, NexGard requires a monthly routine, but the 6-pack means you only reorder twice a year. Some reviewers mentioned that “they don’t make it for humans” as a joke, but the product’s real-world effectiveness against ticks in particular is well-documented in user reports.
