Be mindful and check your dogs. π
The levels of ticks in the UK peak in the autumn. These weird little bugs might not look like much, but they can cause serious issues for both dogs and humans. So, why are vets so fussed about ticks?
Ticks are parasites that feed on mammals (warm-blooded animals - including dogs, cats, and humans!) by attaching to their skin and drinking their blood and tissue fluid. They will usually attach to a dog for a few days at a time, drinking until they are full and swollen, and then dropping off to digest and find their next host.
There are around twenty different species in the UK, but Ixodes ricinus, the Deer Tick in this picture, is the most common. The tick you see here is large and full after feeding - they are much smaller when they first attach themselves.
So, why are ticks a problem for our dogs? Well, tick bites can be painful or irritating, and may become infected after the tick has finished feeding. Our vets often see dogs with these kinds of bites, and they may need medication to treat the infection or relieve the pain and irritation.
More worryingly, however, ticks can pass on various blood-borne illnesses from their bites. The most common of these is Lyme Disease (also called Borreliosis), which causes fever, weight loss, lameness and kidney damage if left untreated. There have also been cases of Babesiosis in the UK, which can cause fever, jaundice, weakness and collapse.
Thankfully, most tick bites in the UK will not lead to dogs becoming sick. However, most tick-borne diseases are serious illnesses which can be fatal, so it is better to prevent them if possible. If you travel abroad with your dog they may be at increased risk as these illnesses are more common in some other countries.
Humans can also suffer from tick bites, and there is concern that ticks which drop off dogs (or cats!) in the home may then attach to other family members. Lyme disease is a problem in humans, too, so there is a potential risk from any tick bite.
Cats seem thankfully to be much more resistant to Lyme disease or other tick-borne illnesses, though this is still a theoretical risk from this.
There is a range of different ways to protect your dog (and cat) from ticks. You may be able to find and remove them on short-haired dogs using a tick hook or tweezers β but they are very small when they first latch on, so can be hard to spot! Some flea spot-one, tablets and collars are also effective against ticks β but not all of them! Speak to a vet or nurse to find out whether your petβs current treatment is doing the trick.
