Lyme Disease In Dogs: Signs You Shouldn’t Miss

You wouldn’t be the first to wonder if you can pick up on an illness from your furry buddy. But while Lyme disease in dogs thankfully doesn’t tend to pass from animals to humans, it can still be fatal if left untreated. So if you’ve ever thought those pesky ticks outdoors were just a nuisance, think again. Here’s how to spot the signs – and how a smart dog tracker can help you spot potential health issues early.

Key Takeaways

Common signs of Lyme disease in dogs include lameness (often shifting between legs), fever, lethargy, swollen joints, loss of appetite, and in severe cases, kidney issues. Symptoms can appear weeks after a tick bite.

Use tick prevention products, check your dog’s coat after outdoor walks (especially in grassy or wooded areas), and keep lawns trimmed. Vaccines may be available in high-risk regions – ask your vet if it’s right for your dog.

The Tractive GPS & Health Tracker allows you to monitor your dog’s vital signs, activity, and rest patterns, helping you detect early signs of fatigue or unusual behavior that could indicate infection. So you can take action early and get them to a vet on time.

What exactly is Lyme disease in dogs?

Lyme disease is a tick-borne bacterial disease that infects both dogs, cats, and a host of other animals. It’s caused by the bacterium, Borrelia burgdorferi, which lives in the salivary glands of infected black-legged ticks and western black-legged ticks.¹

Sadly, adult ticks tend to be active from March to mid-May – but also from mid-August all the way to snowy November. Both young ticks (called nymphs) and adults can transmit Lyme disease. Even worse, most adult ticks are only around the size of sesame seeds. So they might not be easily visible – and you might miss out on them if you aren’t grooming your dog on the regular.

Importantly, not all ticks are carriers of Lyme disease. These parasites only pick up the infectious bacteria if they feed on the blood of rodents or deer that already have it. From where they can spread it to other animals – and even humans.

Can I get Lyme disease from my dog?

Well, both yes and no. Firstly, your dog (or cat) isn’t likely to give you any ticks directly.² Humans don’t tend to be the best hosts for these species of ticks in general.

However, your dog might still bring home some black-legged ticks clinging to their fur. Which can spread around your home and backyard – and eventually infect you as well. Some other species of ticks, like deer ticks (Ixodes scapularis) can infect both humans and dogs from your walks outdoors.

So it’s important to figure out…

What are the first signs of Lyme disease in dogs?

Sadly, the symptoms of Lyme disease in dogs might be quite easy to miss – since they tend not to be as specific as you might expect.³ In fact, these signs might not emerge until 3-30 days after the tick bite. Including:

• Lethargy,
• A loss of appetite,
• Fever,
• Swollen lymph nodes,
• Swollen joints, which might make it difficult for your dog to move around as easily,
• A skin rash, after a few weeks

Now on the bright side, your dog might not necessarily fall sick – even if bitten, especially if they’ve got a strong immune system. The bacteria does take a while to spread around, after all.

⚠️ However, left untreated, Lyme disease can be fatal – damaging your buddy’s kidneys, nervous system, and heart. In other cases, it can even lead to paralysis and seizures, if it affects their nervous system.

How your vet might diagnose & treat your buddy

If you’ve brought your dog (or dogs) over to the vet, they’ll first start by checking your dog’s medical history and measuring their antibody levels. A high level of antibodies – and matching symptoms – might indicate your dog’s immune system is already on “fight” mode against the spread of harmful bacteria.

Your vet might also recommend other diagnostic tests to rule out other serious health conditions like a kidney infection. (Which might have similar symptoms.) Based on what’s causing your buddy’s symptoms, your vet might recommend:

• Antibiotics to deal with any infection, over weeks or even months, depending on the severity of the case,
• Anti-inflammatory medication deal with any swelling or pain,
• Physiotherapy to help your buddy with any mobility issues,
• A change in diet to help boost your dog’s immune system and help them get better faster.
• Special supplements to help with any joint pain.
• Avoiding any strenuous activity and plenty of rest as your dog recovers.
• Any followup treatment, as required – especially to monitor your dog’s symptoms.

Where is my dog likely to run into ticks?

Spring and summer tend to be peak tick months – but don’t let your guard down during the cozy fall or winter months either. Ticks are tenacious little critters and can be active throughout the year, waiting for your dog to pass by and latch on to their fur. Here’s where your buddy might run into them, by season:

Season	Where your dog might encounter ticks
Spring and Summer	– Wooded areas and forests with plenty of underbrush, where your buddy might run into deer ticks. (The type most likely to spread Lyme disease!) Likewise, any areas you run into woodland animals, like mice, chipmunks, and other small mammals. – Tall grasses and bushes in fields, meadows, lawns, shrubs, and even your own backyard. Ticks tend to wait on the edges of long grasses and bushes to latch on to animals and people passing by. – Leaf piles, especially those leftover from the fall months. (Especially if they’re already decaying.)
Fall	– Trail edges and pathways, especially those with tall, unkempt grass and thick, dense vegetation. This could include your regular hiking trails or running paths. – Suburban parks and urban green spaces with shrubbery, especially in bushes or ground cover where you might also get deer or other rodents. (Which your dog might end up rooting out for by digging holes everywhere!) – Farm areas, including livestock or near barns with animals like mice and deer. All of which open up your dog’s risk of picking up some ticks.
Winter	– Wooded areas, especially in warmer zones or spots with leaf litter. – Wildlife corridors or woodlands near your property where deer might still roam. (Though tick activity does fall during winter, it doesn’t stop 100%. So you’re still best off being careful.)

How you can prevent your dog from developing Lyme disease

No human and certainly no dog is safe from ticks – that’s for sure. But on the bright side, Lyme disease in dogs doesn’t tend to develop overnight. Usually, the tick has to be attached to your dog for around 16-36 hours to transmit any disease.

So here are a couple of steps you can take to prevent any bites from worsening into a full-blown disease:

Make regular grooming (and checkups) a priority

With a regular brush and a quick wash of their feet and fur once you’re back home from a walk, you can catch on to ticks easier – much before they’ve had a chance to infect your dog. So make sure to do a quick brush through your dog’s fur once you’re back home from any walks, hikes, or runs in any wooded areas. (Or even your lawn, for that matter!)

Figure out how to remove a tick properly – if you see one

Now if you’ve been brushing out your buddy’s coat on the regular, you might just catch on to a tick or two if you’re vigilant. But how to remove it safely if you do? Unfortunately, it’s not as simple as wrestling it out with a set of pliers. If you haven’t removed the tick properly, its head might get stuck in your dog’s skin – continuing to transmit diseases or cause inflammation via its salivary lands. (Eww, we know!)

So rather, you should:

• Keep a container of alcohol or rubbing alcohol ready. If you have rubber gloves at home, put them on.
• Ask a second person to help you. (Especially to keep your dog calm and hold them, if they’re already restless, anxious, or scared.)
• Separate your dog’s fur with your fingers so you can see the tick clearly.
• Use a pair of tick tweezers or a tick snare to position around the tick’s body. Stay as close to your dog’s skin as possible. (And no, your regular human tweezers won’t help!)
• Gently twist and pull the tweezers or snare to remove the tick.
• Check that the tick’s mouth parts aren’t still attached to your dog’s skin.
• Place the tick in the container with alcohol or rubbing alcohol. Keep it there for a few days. If your dog develops a disease, it can help your vet identify it for a correct diagnosis.
• Disinfect the tweezers or snare after use.
• Wash your hands extra.

⚠️ Head to your vet if you notice the tick’s mouth parts still attached or any swelling or redness in your dog’s skin.

Give your yard a trim & your fencing a check

Ticks tend to infect mice, chipmunks, deer, and other small mammals most commonly. All of whom tend to spend time around moist, dark, secluded areas – where they have plenty of space to hide. Which could, sadly, also include your yard, unless you’ve taken steps to prevent them from gathering here.

Meaning, generally, the trimmer your yard, the less likely it is you’ll have ticks.⁵ So you should:

• Keep your grass mowed and remove any leaf litter and weeds periodically.
• Fix up any holes in your fencing that might attract rodents. (Or tempt your dog to escape through them!)
• Avoid using plants that attract deer.
• Keep any tree branches and shrubs trimmed to let in more sunlight.

Get your dog the jab

Thankfully, a Lyme disease vaccination for dogs can help prevent infections from specific tick species. It’s a good idea to get these done at your vet’s clinic around spring, which tends to be peak tick season. The basic immunization plan usually includes two vaccinations given a few weeks apart. After that, your dog might need annual booster shots to keep their immune system strong.

Your vet can also best advise you whether your buddy could benefit from a tick collar, spot-on treatment, or other medication to prevent an infection.
