The insect growth regulator, which is known as pyriproxyfen, was added to the formula to make it a more complete flea and tick killing solution. The IGR ingredient makes it possible to kill fleas and ticks in all of their life stages. This is the main difference between regular K9 Advantix and K9 Advantix II.

Effective flea treatment kills 98-100% of the fleas on dogs within 12 hours and continues to prevent infestations for at least four weeks and kills fleas before they lay eggs. Larval flea stages in the dog's surroundings are killed following contact with a K9 Advantix II.

The biggest difference between these medications is that K9 Advantix II kills AND repels fleas, ticks, mosquitoes, and chewing lice, but Frontline Plus kills these pests AND prevents fleas from laying new eggs. Pregnant dogs are also approved to use Frontline Plus, and vets must be consulted to use K9 Advantix II.

What if my dog licks K9 Advantix? Ingesting a small amount of K9 Advantix is unlikely to cause serious symptoms in dogs, but it can still lead to mild to moderate side effects such as excessive drooling, nausea, vomiting, diarrhea, lethargy, and lack of coordination.

within 12 hours How long does it take for K9 Advantix® II to work on fleas? K9 Advantix® II kills fleas within 12 hours. New fleas that jump on the dog from the surroundings, such as grass, carpet and pet bedding, are killed within 2 hours with protection against further infestation for at least 4 weeks.

four weeks A single application of K9 Advantix® II remains effective for four weeks. However, if the dog has a severe infestation, retreatment within a month may be necessary. Do not retreat more than once every seven days. After flea control is attained, return to a monthly treatment schedule.

How quickly does Advantix work? Advantix stops fleas biting within 3 to 5 minutes and kills both adult fleas and larvae within 20 minutes. Fleas are not required to bite the animal to receive a lethal dose. Ticks already on a dog at the ime of treatment will be killed but remain attached and visible.

K9 Advantix II Extra Large Dog is the veterinarian-recommended formula that helps defend your dog against five pests: fleas, ticks, mosquitoes, biting flies and lice. And unlike other treatments, K9 Advantix II kills and repels fleas, ticks and mosquitoes.

K9 Advantix II is a top veterinarian-recommended brand because it repels and kills all life stages of fleas (eggs, pupae, larvae, and adult fleas) and ticks (Deer ticks, American dog ticks, Brown dog ticks, and Lone Star ticks).

How long do I have to wait to bush him and is that fur toxic? Once the treatment has been absorbed by the dogs' coat and they're fully dry, normally between 1-5 hours depending on the environment, the treated area should be safe for anyone to touch.

Dogs treated with Advantix will be less likely to be bitten by mosquitoes or flies. Most veterinarians consider Advantix safe for dogs, but it is a strong medication that should be used with caution. The main active ingredients are imidacloprid and permethrin, both of which can be toxic in high doses.
