about parasites

Parasites can aggravate your dog and
affect the way you play and bond with
each other. More importantly, they can
put your dog's health at risk.

K9 Advantix® II is for use on dogs only.

Tick Distribution Map

In dogs, ticks are known to potentially transmit the organisms that can cause diseases such as Lyme disease, ehrlichiosis, Rocky Mountain spotted fever, babesiosis, tularemia and anaplasmosis.

K9 Advantix® II REPELS and kills ticks, including:

  • Deer ticks (vector of Lyme disease)
  • American dog ticks (vector of Rocky Mountain spotted fever)
  • Lone Star ticks (vector of ehrlichiosis)
  • Brown dog ticks (vector of ehrlichiosis)

Ticks are a common parasite that feed on dogs. Tick species are found worldwide and may infest dogs in very large numbers, especially during certain times of the year. These blood-sucking parasites are often found in tall grass, where they can attach themselves to a passing animal. Ticks require physical contact to infest your pet. Harpoon-like mouth parts allow them to anchor firmly in place while sucking blood from their animal host.

Ticks also act as vectors of disease. Infected ticks can carry and transmit the organisms that can cause Lyme disease, Rocky Mountain spotted fever, several types of ehrlichiosis, and other potentially deadly diseases. A single tick can carry several disease-causing organisms at the same time.

Your dog's risk from tick infestation may be increased if

  • Tick-borne diseases have been diagnosed in your region
  • You take your dog camping, hiking, or hunting in wooded or undeveloped areas
  • You have seen a tick on, or previously removed one from, your dog
  • Your dog is exposed to wildlife that are natural hosts for ticks (deer, rodents, raccoons, etc.)
  • Your yard has dense shrubs, tall grass, or leaf litter—common tick habitats
  • You take your dog to wooded areas or grassy meadows
  • Your pet is not on a tick control product

Tick life cycle

  1. Eggs - Female lays eggs off host. Eggs hatch to larvae.
  2. Larvae - Larvae feed on dogs or small mammals. Larvae leave host and molt into nymphs. Infected larvae can transmit disease causing organisms.
  3. Nymphs - Nymphs feed on dogs or small mammals. Infected nymphs can transmit disease-causing organisms as they feed.
  4. Adults - Adult ticks feed on the host. Infected adults can transmit disease-causing organisms as they feed.

Besides being an annoyance to your pets, fleas also can lead to disease, tapeworms and flea allergy dermatitis (FAD) that can result in hair loss, skin inflammation and irritation, and severe scratching. In large numbers, fleas may cause anemia from blood loss, which can even be fatal in severe infestations.

Flea life cycle

The average flea life cycle takes between 3 and 4 weeks, but can last 180 days (6 months) depending on temperature and humidity.1

The flea life cycle

1. Eggs
Female lays up to
40-50 eggs in one day.2
Eggs fall off into the
environment. Eggs
hatch into larvae within
2 weeks.

2. Larvae
Larvae feed on flea
fecal matter in the
environment. Larvae
can ingest tapeworm

3. Pupae
Within five to eleven days,
larvae form a cocoon and
pupate. Adult fleas
emerge from the pupae
and begin feeding as
soon as a host is found.

4. Biting Adults
Adult fleas feed on host.
Females need a blood meal
to reproduce. Fleas may
transmit disease-causing
organisms during feeding.

K9 Advantix® II REPELS and kills mosquitoes

The problem with biting mosquitoes:

  • Biting mosquitoes are irritating to dogs, causing them to scratch, which can lead to secondary skin infections.
  • Stress from biting can be severe with large populations of mosquitoes.
  • Mosquitoes can be a carrier of viral and parasitic disease organisms, including heartworm.1

Mosquitoes are found all across the United States and can be a year-round concern where temperatures and humidity remain favorable throughout the year. While most mosquitoes are merely an annoyance, they can spread viruses and parasites to animals.

Some tips for reducing mosquito exposure:

  • Keep pets indoors during early morning and evening hours when mosquitoes are most prevalent.
  • Only use mosquito repellent that is approved for use on pets to help prevent bites. Check the label to
    determine if the product is for use on pets or ask your veterinarian for a
    recommendation. Many insect repellents that are designed for human
    use contain chemicals that can cause serious health risks in animals
    and therefore should not be used on your pet.

Biting flies


K9 Advantix® II repels and prevents blood-feeding by biting flies. Biting flies can cause severe stress to dogs. Irritation of wounds through persistent scratching can lead to secondary infections.

Chewing lice

K9 Advantix® II treats, prevents and controls
lice infestations.
