Disease-carrying ticks can pose serious health risks to both dogs and people, no matter what state you live in. The U.S. Centers for Disease Control (CDC) reports that ticks in every state can carry disease, and the number of tick-borne diseases is on the rise. Here in Northern California, they seem to be everywhere, and it is not uncommon for me to find an “incidental tick or two” during my physical exam. This usually leads to a tick-related conversation where I sometimes have to dispel a tick myth or two.
Fiction: “I heard that the best way to remove a tick is with a lit match, petroleum jelly, or alcohol”
Fact: None of these methods cause a tick to “back out” of the skin and can actually cause more injury. When you try to remove an embedded tick in this manner, you can actually aggravate it, causing the tick to deposit more disease-carrying saliva into the wound, and increasing the risk of infection. The best way to remove a tick is by using tweezers, grasping it as close to the dog’s skin as possible, and pulling the tick out with a steady motion. Dispose of the removed tick down the toilet or by placing it in rubbing alcohol.You should clean the skin with mild soap and water after its removal. You may see a little red circle (like a bull’s eye) or bump of redness on the skin at the insertion site following removal- this can be normal and may be visible for up to a couple of days. You should see your veterinarian if the region of redness increases in size or if it doesn’t go away within 2-3 days.
Fiction: “My dog doesn’t go hiking in the woods, so I don’t have to worry about exposure”
Fact: Ticks live on the ground no matter the locale, and this includes our urban parks and rural areas. Ticks typically crawl up blades of grass, looking to hitch a ride as our pets pass by. Ticks like to migrate upward, which is often why they’re found on the head.
Fiction: “Ticks aren’t a problem in the colder weather, so I only have to worry in the summer”
Fact: In most areas of the country, “tick season” runs from April to November, however, infection can occur any time of the year. For example, in the winter, some tick species actually move indoors, while other species make a type of “internal antifreeze” to survive during the winter months. This is often why veterinarians will recommend year-round tick prevention.
Fiction: “Lyme disease is the only illness that ticks can transmit to dogs (and their humans)”
Fact: While Lyme disease is the most widely known and common disease caused by ticks, there are other diseases including Rocky Mountain spotted fever, babesiosis (one of the newer discovered diseases, see Jane Brody’s article  about it), and ehrlichiosis. These diseases can have equally devastating effects on our pets.
Fiction: “If I find a tick on my pet, or if I see the “bull’s eye” red ring on my pet’s skin, I should get a blood test because this will tell me if my pet has disease”
Fact: If your pet is ill, and you are aware of tick exposure, a tick-borne disease screen is highly recommended. However, it should be noted that lab tests run for tick-borne diseases are often negative on the first sample and require a second test in two to three weeks to confirm infection. Therefore, a negative test does not necessarily mean that your pet is free from disease. It should also be noted that many dogs with tick-borne illness do not experience any symptoms, especially in the early stages of disease.
And one last tip to throw into the mix: if you do attempt to remove a tick at home, make sure that it is actually a tick! I cannot tell you how many times I see a pet on emergency for an accidentally removed nipple! Ouch!
