This formula also kills fleas which may cause Flea Allergy Dermatitis and flea bite anemia. That’s why K9 Advantix II Large Dog topical, spot-on formula makes application simple - going on in seconds. It's easier than a flea collar and there are no hard-to-swallow pills. You’ll also love that K9 Advantix II is fragrance-free and waterproof after 24 hours of application. Check the product label for information on application and potential side effects. K9 Advantix II pest protection is effective on both indoor and outdoor dogs. Your dog should be at least 7 weeks old and weigh to use K9 Advantix II Large Dog.

Durable and fun!
Color: Michigan Wolverines
I’m impressed with this toy! My two puppies absolutely love it and it’s been a hit during playtime. What stands out the most is how durable it is. This toy has held up much longer than most of the others I’ve tried. Despite my puppies energetic play, it’s still in great shape! Plus, it’s the perfect size for them to carry around and chew on. Definitely a must-have for any Michigan fan with pups!

A Touchdown Toy for My Pups!
Color: Michigan Wolverines, Style: NCAA #1 Fan Toy
This has been a huge hit in our house! As a die-hard Michigan fan, I was thrilled to find a toy that combines my love for the Wolverines with my puppies playtime. The toy is well-made, durable, and the perfect size for fetch and tug-of-war games between my two pups.
Not only is it tough enough to withstand some rough play, but it also holds up well after multiple washes. If you're a Michigan fan and want to spoil your furry friend with a toy that's both functional and fan worthy, this is the perfect choice.
Go Blue and go fetch!
