Each application provides up to 30 days of protection against fleas, ticks, and mosquitoes. This monthly treatment ensures continuous defense, ideal for active dogs exposed to outdoor environments year-round.

Waterproof Formula

K9 Advantix remains effective even after swimming or bathing, thanks to its waterproof design. This durability ensures consistent protection for water-loving dogs, maintaining efficacy in wet conditions.

K9 Advantix Reviews

Our satisfied customers have found K9 Advantix solutions to be remarkably effective and user-friendly, as evidenced by the following reviews:

I started using K9 Advantix Large Dog Treatment (21-55 lbs) for my Lab, Rusty, after a tick scare last summer. It’s so easy to apply—just part the fur and squeeze. Within a day, I noticed no more scratching, and we’ve had no fleas or ticks since. Rusty loves swimming, and the waterproof formula holds up perfectly. The tube’s a bit tricky to open, but the results are worth it. K9 Advantix keeps Rusty happy on our hikes!

My Chihuahua, Bella, is only 8 lbs, so I was nervous about flea treatments, but K9 Advantix Small Dog (4-10 lbs) is perfect. It’s vet-recommended, and Bella hasn’t had a single flea since we started. The application is quick, and it doesn’t irritate her skin. We live near a park, and it repels mosquitoes, too. I wish the scent was milder, but it fades fast. K9 Advantix gives me peace of mind for my tiny pup!
Sofia Lopez
I’ve been using K9 Advantix XL Dog Treatment (over 55 lbs) for my German Shepherd, Max, for a year, and it’s a lifesaver. Max is always in the woods with me, and this keeps ticks and fleas away, even after he rolls in mud. It’s waterproof and lasts a full month. The eco-friendly packaging is a nice touch. Sometimes the liquid spreads unevenly, but it still works great. K9 Advantix is a must for active dogs like Max!
