Sentry Fiproguard Plus Flea & Tick Dogs 23-44 lbs, 6-Month

My dog comes in from the yard looking like she has personally investigated every square inch of the property. Flea prevention is not optional in this house. It is infrastructure. This is the 23 to 44 lb dog version of Fiproguard Plus, and like the cat formula it uses the same active ingredients as Frontline Plus: fipronil to knock out adult fleas and ticks quickly, and (S)-methoprene to interrupt the flea life cycle at the egg and larvae stage. One tube per month, applied to the skin at the base of the neck or between the shoulder blades, and protection runs for 30 days. The formula is waterproof, which matters for dogs that do not understand the concept of staying dry. The six-dose pack gives you a full half-year of coverage, and the per-dose price is meaningfully lower than name-brand alternatives. Performance has been consistent with no breakthrough flea activity and no visible skin irritation at the application site. Make sure to weigh your dog before purchasing to confirm the 23 to 44 lb range is the right fit. Going over or under the correct weight range is worth avoiding. Application is quick once you have done it once, and most dogs tolerate it well. Reliable, affordable, and easy to use. For medium-sized dogs in the target weight range, this is a strong pick for monthly flea and tick prevention.

Awesome flea meds. The only brand I've ever used or needed. Over 10 years of no fleas.

We don't live in the woods but we do take the dog hiking a lot. I never had a flea or tick problem with my dog (used this for about a year), but I have decided not to get this product any more. After talking with the vet, I found out that this only kills the fleas/ticks if they bite. I'm going to use a different brand that repels and kills before they bite. Its more expensive, but I worry about him getting sick from a tick bite. But if you don't take your dog into the woods, they you will probably be fine.

I've been using this on my puppy. I take them out a lot and the yard is surrounded by families with their own pets, and she has zero fleas nor ticks. June 2024, so over a year and no fleas still, despite interacting lightly with stray cats.

Been using this for years. Works great even during peak flea season in the south

Tried this first app no help second still fleas not too impressed

I am sold on keeping my dog tick free and Sentury is an affordable way to do that.

The scratching stopped at the first treatment on my doggy's neck. It's a little pricey but worthy, for it prevents the animal's suffering from itching.
