pet questions

What is the difference between K9 Advantix® II and Advantage® II for dogs?

K9 Advantix II repels and kills ticks, fleas, biting flies, mosquitoes and lice while Advantage II for dogs offers flea protection only.

Is there a difference between K9 Advantix® II and and Frontline® Plus for Dogs?

Frontline Plus kills only ticks, fleas and lice. It does not REPEL any of these and it is ineffective against mosquitoes and biting flies. Bayer, the makers of Advantix, reminds us REPELLING parasites before they attach can minimize the opportunity for ticks, fleas and lice to transmit disease to your pet.

Is there an Advantix for Cats?

No. Advantix is intended for use on dogs only. For cats, we offer the lowest prices on Advantage II for Cats which is effective at eliminating fleas, mites, ticks and other skin parasites on cats.
