Your dog could be bringing a hidden danger into your home
“Without a product that repels or kills ticks on contact, your dog could be bringing a danger into your home.”
Let me explain.
As a veterinarian my focus had always been on preventing Lyme disease in dogs. I had always thought that when a tick crawls onto a dog it posed little risk to the owner, just the dog.
How wrong I was.
Here is the real life scenario that I witnessed this past fall that I think all people should be aware of as it opened my eyes to a hidden danger.
A mother and her adult daughter went for a one-hour walk in a ravine with their dog Scruffy. They then got into their car and drove home. While having coffee in their kitchen the daughter noticed a bug crawling on a chair, then another on the wall. They were ticks!
“Where did the ticks come from? What are they doing in our house, don’t they live in the woods?” they wondered. Then it came to them, “The dog!”
They checked Scruffy they found another two ticks imbedded in the skin behind his ears. This is when we got involved. We removed the ticks. They were Deer Ticks, the kind that carry Lyme disease. Worse, the ravine that they had been walking in was known to have ticks carrying Lyme disease. This was a real danger.
This puzzled and concerned me. I had always assumed that a tick, once it crabbed hold of a dog’s fur and climbed aboard would waste no time in latching on but two ticks had spent part of the walk and the car ride home wondering over the dog and had fallen off in their home. Why had they not attached to the dog?
Researching this I found the answer.
Ticks are programmed to try and attach around the head, neck, and ears where the skin is thinner and the dog has more trouble grooming so that there is less chance of them being removed. They cement themselves in place once they attach so, unlike a flea who bites and moves, a tick is committed to the spot it selects. It wants to make sure that it is a good one.
This means that after a weekend walk in the woods or long grass, a dog could pick up ticks and drop them in the owner’s car or home.
These ticks or nymphs (immature stages the size or a grain of sand to a poppy seed) would then be free to attach themselves to the unsuspecting people or children in the home or be waiting in the car for the husband or wife to set out Monday morning for work. They would then crawl up the unsuspecting driver’s neck and attach in their hairline where they would be difficult to detect especially if they were the tiny nymphs. Undetected they could pass Lyme disease onto the owner without treatment being initiated.
This frightened me. This is a huge extra risk for owners that many are not aware of. My focus had always been on protecting the dog and we can do this with vaccines and topical or oral tick medications, but this illustrated that your dog can actually bring ticks into your car and house that are still looking for a host. Avril Lavigne contracted Lyme disease and has no idea when or how she was bitten. Could a tick have hitched a ride to her home on her dog?
So what can we do?
One solution is to apply a tick treatment to the dog that repels ticks and kills ticks on contact so that they do not climb aboard the dog to be transported into the car, or if they do climb on the dog they come in contact with a pesticide and even if they drop off in the house they will die and not pose a danger to the home owners. Another is to carry a lint roller in the glove compartment and run it over the dog before getting into the car. This will pick up the tiny nymphs and adults.

disease are spreading, ticks don’t care who or what they bite so it is important that we do all we can to prevent our families from being bitten.
Lyme disease is real, it is not just something we read about. Here is a list of some famous people who have contracted Lyme Disease: Avril Lavigne, Yolanda Foster, former President George Bush, Amy Tan, Aleck Baldwin, Jamie Lynn Sigler, and Rebecca Wells.
Make sure you know the danger and how to protect yourself and your pets.
Things to know about ticks:
1) Only the blacklegged tick or ‘Deer tick’ carries Lyme disease.
2) Deer ticks come in three sizes. Larvae, the size of a grain of sand, nymphs, the size of a poppy seed and adults, the size of a sesame seed. This means that they can be difficult to find especially as they crawl under clothing and latch on in hard-to-see places.
3) Ticks crawl up, they don’t jump or fly or fall from trees.
4) You have 24 hours to find and remove a deer tick before it can transmit Lyme disease so early detection is key.
5) Ticks can be active even in winter. We have had owners find ticks on their pets in January or February on warm sunny days where the temperature hovers around 4°Celsius.
Health officials recommend that Canadians be aware of the risks of
Lyme disease and take precautions. Here is a list of 9 precautions that you can take:
1) Cover up with light-coloured clothing to spot ticks more easily.
2) Wear closed-toed shoes.
3) Tuck your pant legs in to your socks to prevent ticks from crawling up your legs.
4) Tuck your shirt in to prevent ticks from getting on to your skin.
5) Use insect repellents that contain DEET or Icaridin.
6) Shower or bathe within two hours of being outdoors to wash away loose ticks.
7) Do daily “full body” checks for ticks on yourself, your children and your pets. Use a lint roller.
8) If you find a tick on your skin, remove it within 24 to 36 hours.
9) Apply a tick repellent to your dog so that he/she isn’t a source of entry into your home for the ticks.
