We had our first Lyme positive test of the year!!
This is a good reminder about why it is so important to have your dog tested annually with a 4Dx🩸and to keep your pets on tick prevention any time temperatures are above zero!
This dog is currently showing no obvious symptoms (95% of Lyme positive dogs are asymptomatic), but there’s some additional testing we need to do to determine if treatment for Lyme disease is needed. 🔬
Some fast facts about 4Dx testing, Lyme disease, and ticks:
⚡️The 4Dx test checks for antibodies to Lyme disease and two other tick borne diseases, which tells us if a dog has been exposed to these diseases and has developed antibodies. Positive dogs often remain positive for years. 🦠
⚡️The test also checks for heartworm antigen, which tells us if a dog is currently carrying heartworm. Heartworm is thankfully very rare in dogs that live in Canada and do not travel to high risk areas. 🪱
⚡️The 4Dx test only requires a few drops of blood and takes 8 minutes to get results! ⏱️
⚡️The most common symptoms of Lyme disease in dogs are fever, lethargy, joint pain/lameness, and damage to the kidneys (we check for this by testing for protein in the urine). 🩺
⚡️The scientific name for Lyme disease is Borrelia burgdorferi. 🧫
⚡️Lyme disease is spread by Ixodes scapularis, the black legged deer tick. These ticks are most active in the spring and fall and prefer environments with lots of leaf cover like trails and forests. 🍂
⚡️Ticks can be active any time temperatures are above zero, regardless of what time of the year it is. All it takes is one warm day and one tick! We recommend using prevention from at least March to November (and consider all year round) 🌡️
⚡️Using safe, effective, fast acting tick prevention (whether topical or oral) is the best way to prevent the spread of tick borne disease. Lyme disease takes about 24hrs to transfer from a tick to a dog so fast acting prevention is key! We recommend only using prescription products provided by your vet (or K9 Advantix which is also available at pet stores). We do NOT recommend brands like Hartz and Zodiac due to concerns over safety and efficacy. 💊
