Lyme Disease and What You Need to Know

Lyme Disease and What You Need to Know.
Courtesy of Life's Abundance and the May 2018 Newsletter:

If you’ve ever had the displeasure of finding a tick on your pet, you know how revolting they are. The first time I found one on my Golden Brody, I was petting him when I felt what I thought was a skin mass. When I looked closer I found to my horror that it was a huge, engorged tick. We had just moved to another part of the county a month prior; in our previous home we never had a tick issue, so I was using just a flea and heartworm preventive. That changed quickly!

Which brings up a couple of points. First, as gross as ticks are, the bigger concern here is that they carry a variety of diseases that can negatively impact your pet’s health. The most prevalent of these tick-borne diseases is Lyme disease. Second, even within relatively tiny geographical regions, the parasite risk can vary tremendously. If you read last month’s blog post on heartworm disease, you’ll remember this trend of microclimates combined with two years of hot, wet weather has created a huge increase in the prevalence of heartworm in areas where they were never a problem before. The same goes for fleas and ticks.

If you haven’t heard of the Companion Animal Parasite Council (capcvet.org), bookmark their site now. It has the most comprehensive parasite data available. Although it’s geared towards veterinarians to help them educate clients, you can absolutely use and share this wonderful resource with your pet parents friends. It's an invaluable tool for assessing the specific risks in a particular geographic location.



Lyme disease is transmitted through the bite of an infected tick. It affects both pets and people, but it is not transmitted to you directly from your companion animal. A bacterial disease, symptoms begin with headaches, fatigue and fever, but it can progress throughout the body and negatively impact multiple organ systems if left untreated. Because the signs are so vague, many cases are left undiagnosed for a very long time. For more detailed data about its symptoms, visit cdc.gov/lyme/signs_symptoms/index.html.

The CAPC just released their 2018 Parasite Forecast, and it’s got some bad news about Lyme disease. As the tick population has spread, so has the incidence of Lyme disease. While veterinarians in the northeast are well-versed in recognizing signs, it is becoming a much bigger problem in areas such as the Dakotas, Iowa, Missouri, Illinois, Kentucky, Virginia, Tennessee and North Carolina. It may not even be on the radar for most people who live in these areas, but it should be.

The data is so specific that you can click on your state and find the statistics by county - how many pets were tested for Lyme and how many came back positive. As a well-informed pet parent this is invaluable if you find a tick on your pet. It can help you answer questions like "should I tell my vet?" and "should I really pay for the test?" We encourage all of our readers to search the database, available here: capcvet.org/maps/#2018/all/lyme-disease/dog/united-states.



But it’s not all bad news! Once diagnosed, Lyme disease can be treated with a course of antibiotics. And there’s plenty that you can do right now! First, be aware of the risk in your specific area. Second, use a good tick medication. You have choices ranging from monthly spot-ons to collars and even oral medications available from the vet. They are all quite effective, so it’s a matter of personal preference and what works best for you. There is a vaccine as well. If you live in a Lyme endemic area, talk to your vet about whether the Lyme vaccine is a good option for you.

And mostly importantly, check your pet for ticks, especially in the areas where they like to hide: under ear flaps, between the toes and in the armpits. Removing ticks promptly decreases the risk of Lyme disease, as most cases of transmission occur when the tick has been attached longer than a day.

Fortunately for us, Brody’s tick issue was a one-time affair. From that day forward for the rest of his life, he was on year-round prevention. As soon as Dakota hit the weight limit for the preventive I wanted to use, I started him on tick prevention as well. I check him every day but so far all I find are little burrs from his rolling around in the grass. Hopefully it stays that way!

Lyme Disease

Great read by Dr. Jane Bicks from the July 2014 Life's Abundance Newsletter:

It’s the height of summer, which means that mountain trails, bucolic meadows and forested thickets are beckoning your dog to romp and explore. This impulse may be at odds with concerns about new research on Lyme disease, which may have you more inclined to restrict your canine companion’s activities to the Great Indoors. Before you put the kibosh on outdoor fun, make sure you know all the facts about canine Lyme disease. According to Banfield Pet Hospital’s 2014 State of Pet Health Report, based on the medical data from over 2.3 million dogs, incidence of canine Lyme disease has increased 21% since 2009.

 As of last year, one in every 130 dogs carries the disease-causing bacteria. The risk of Lyme disease depends on where you live. In New England, Lyme disease rates are much higher than the rest of the country. New Hampshire has the highest rate of Lyme disease cases, with one in every 15 dogs affected! Compare this with Washington and Oregon, where only 1 in 1,000 dogs carried the bacteria. In the last five years, populations of the two species of ticks that carry Lyme disease have skyrocketed. As white tailed deer populations have escalated (chiefly due to declines of predator species), so too have the tick species that feast upon them. This is especially true in states east of the Rocky Mountains.

While much smaller in stature, but just as problematic in the Northeast, the white footed mouse is another carrier of the bacteria responsible for Lyme disease. Greater numbers of animals that attract ticks translates to an increased likelihood that pet kids will be bitten. Lyme disease is caused by the corkscrew-shaped bacteria, Borrelia burgdorferi. The bacteria are carried by ticks which transmit the infection when they feed on animals and humans. The disease can cause generalized illness in animals and humans. Even though about 75% of dogs living in endemic regions are exposed to infected ticks, only a small percentage develop symptoms.

Lyme disease was first discovered in 1975, when an unusual outbreak of rheumatoid arthritis occurred in the children of Lyme, Connecticut. In the U.S. today, it’s the most common disease transmitted to humans by insects, and perhaps dogs as well. Infections can also occur in horses and cattle … even cats. The most common sign of Lyme disease in dogs is arthritis, which causes sudden lameness, pain and sometimes swelling in one or more joints. Other symptoms include fever, lack of appetite, apathy and swollen lymph nodes. In severe cases, the infection can lead to kidney failure, which can prove fatal, although this outcome isn’t common (thank goodness). If your pet kid is diagnosed with Lyme disease, don’t assume that you too are contaminated. Transmission of the illness from companion animals to humans, or vice versa, is highly unlikely. You wear sunblock to prevent sunburns, so why not take preventative measures to deter ticks?

There are many highly effective veterinary products that will kill ticks before they can transmit the bacteria. Just keep in mind that the best way to avoid the problem is to steer clear of tick-infested areas, especially in the spring when young ticks are most active. After spending time outdoors, do a thorough search for ticks, on both yourself and your companion animals. If you locate any, they should be removed carefully with tweezers, pinching the tick near the head, where they enter the skin.

Researchers have learned that infected ticks must feed for about 24 hours to transmit the bacteria to a susceptible animal. That means quick removal greatly reduces the chance of contracting the illness. Fortunately, Lyme disease is easily treated in dogs with antibiotics.

Thank you for all you do to make the world a better place for companion animals.
