Lyme disease in dogs is a real concern, though many pet owners might not realise their dogs could catch it. Lyme disease comes from a bacteria called Borrelia burgdorferi, which ticks pass to dogs through tick bites.

It’s not just about knowing what Lyme disease is—understanding how it spreads gives you a better shot at keeping your dog safe.

Dogs who hang out in grassy or wooded spots face the highest risk. Ticks love hiding in those places.

Early signs of Lyme disease can sneak up on you—limping, stiffness, fever, or low energy are all clues. If you ignore it, things can get worse fast. For more details, check out this page on Lyme disease in dogs.

Key Takeaways

• Ticks in grassy or wooded areas spread Lyme disease to dogs.
• Limping, stiffness, and tiredness are early warning signs.
• Fast action and prevention go a long way in protecting your dog.

What Is Lyme Disease in Dogs?

Lyme disease is a tick-borne illness that hits dogs when bacteria enter their system. It can cause fever, joint pain, and tiredness if you don’t catch it early.

Understanding Tick-Borne Diseases

Ticks pass on diseases to both animals and people. The black-legged tick (Ixodes scapularis, or deer tick) is the main culprit for Lyme disease.

These ticks hang out in grassy or wooded areas and grab onto your dog as it moves through plants. Not every tick bite is a problem, but the risk jumps if ticks stay attached for a while.

Dogs can pick up other tick-borne diseases too, especially in places where ticks are everywhere. Checking your dog for ticks every day, using tick control products, and steering clear of tall grass helps. Ticks are most active in spring and autumn, but honestly, you have to stay alert all year.

Borrelia burgdorferi and Transmission

A bacterium called Borrelia burgdorferi causes Lyme disease in dogs. It lives and multiplies inside ticks before moving into your dog’s bloodstream.

Dogs usually get infected when a deer tick feeds on them for at least 24 to 48 hours. Once the tick latches on, Borrelia burgdorferi travels from the tick’s gut into your dog’s blood.

Watch for fever, reduced appetite, and joint swelling. Sometimes symptoms come and go or move around the body. Removing ticks quickly and using prevention is your best shot at keeping your dog healthy. For more, check out VCA’s article on Lyme Disease in Dogs.

Life Cycle of Deer Ticks

Deer ticks go through four stages: egg, larva, nymph, and adult. Nymphs and adults are the ones you need to worry about, since they’re the most likely to bite dogs.

Nymphs are tiny—about the size of a poppy seed—and really tough to spot. They’re the main Lyme disease spreaders because they stay attached longer.

Adults are still small, but at least you can usually see them. They feed more during the cooler months. Ixodes scapularis ticks can live up to two years and need blood meals to grow.

Dogs are at risk wherever nymphs or adult deer ticks live. Keeping your dog away from tick-heavy zones and checking its fur after walks can help. For more on tick behavior, the Frontline UK guide on Lyme disease in dogs is worth a look.

How Dogs Get Lyme Disease

Dogs pick up Lyme disease after a bite from certain ticks carrying harmful bacteria. Knowing how your dog gets exposed—and which ticks to watch for—makes a big difference.

Exposure to Infected Ticks

Your dog usually gets Lyme disease from an infected tick’s bite. Ticks like grassy, wooded, or bushy spots—places where your dog loves to sniff around.

When your dog brushes against plants, a tick can latch on. Just one bite from an infected tick can transmit Lyme disease.

The bacteria, Borrelia burgdorferi, travels through your dog’s blood and causes a range of health problems. You probably won’t notice when a tick bites your dog—ticks are tiny, and the bites don’t hurt.

Ticks need to stay attached for at least 24-48 hours to pass on the bacteria. Checking your dog after walks is crucial. Ticks are especially active from spring to autumn, but honestly, they can show up whenever the weather’s mild.

Common Tick Species Affecting Dogs

Not every tick carries Lyme disease, but some types are more risky. The main troublemaker is the deer tick, or black-legged tick.

In the UK, the sheep tick is the one to watch—it’s a kind of deer tick. In other places, the western black-legged tick and brown dog tick also matter.

Here are some tick species that can bother dogs:

• Deer tick (Black-legged tick)
• Brown dog tick
• American dog tick
• Lone star tick
• Rocky Mountain wood tick
• Western black-legged tick

Different ticks like different spots. Brown dog ticks might even show up indoors, while deer ticks stick to forests. Each type poses its own risks. Checking your dog regularly helps you find ticks before they cause trouble.

Symptoms of Lyme Disease in Dogs

Catching Lyme disease early makes treatment much easier. Symptoms can start off mild and slowly get worse if you don’t step in.

Early Clinical Signs

The first signs are sneaky. Your dog might suddenly not want to go for walks or may limp, sometimes switching which leg hurts.

Fatigue is common, and your dog might just seem off or less bouncy. Mild fever can show up. Joint pain and stiffness are big red flags, and your dog might look uncomfortable getting up.

Some dogs get swollen lymph nodes near the bite. A loss of appetite is another clue—maybe your dog skips meals or ignores treats. These symptoms might come and go, making it easy to brush them off. For more, check out this overview on the early signs of Lyme disease in dogs.

Common early signs:

• Shifting lameness
• Tiredness
• Fever
• Swollen lymph nodes
• Joint pain
• Loss of appetite

Progression and Complications

If you don’t treat Lyme disease, things can get ugly. Joint pain can turn into chronic arthritis and your dog might limp all the time.

Swollen joints may feel warm and hurt when touched. Some dogs develop kidney issues, called Lyme nephritis. You might notice more thirst, more peeing, vomiting, weight loss, or even signs of kidney failure. Kidney problems don’t happen to every dog, but when they do, they’re serious.

Prolonged fatigue and muscle pain can show up. In rare cases, heart or nervous system issues develop. As things get worse, simple activities can become tough for your dog. You can read more about these long-term complications of Lyme disease in dogs.

Possible complications:

• Chronic arthritis
• Increased thirst and urination
• Swollen or painful joints
• Kidney problems or failure (Lyme nephritis)
• Vomiting or weight loss

Diagnosing Lyme Disease

Diagnosing Lyme disease takes a sharp eye for symptoms and a good look at your dog’s recent history. Testing helps confirm what’s going on and guides treatment.

Veterinary Evaluation and Wellness Exam

Your vet will ask about where you’ve been walking and whether your dog’s been around ticks. If your dog suddenly starts limping, has swollen joints, a fever, or just seems off, let your vet know.

During a wellness exam, your vet will check your dog for ticks, swelling, and pain. The vet might look for:

• Visible tick bites
• Swollen, painful joints
• Limping or shifting lameness
• Fever
• Changes in behaviour

Since these signs can show up in other illnesses too, your vet’s assessment helps rule things out and decide if more testing is needed. An accurate diagnosis of Lyme disease depends on both the physical exam and your dog’s recent experiences.

Laboratory Tests and Interpretation

After the exam, your vet might suggest blood tests to check if your dog has Lyme disease. These tests look for antibodies to Borrelia bacteria, the culprit behind the illness.

The main types of tests include:

• Screening antibody tests (like the SNAP test)
• Confirmatory tests (such as Western blot or ELISA)
• Advanced tests (like the Lyme Multiplex assay) for tracking infection stage and response to treatment

If your dog tests positive, it means their immune system has encountered the bacteria. But that doesn’t always mean your dog is actually sick. Vets interpret test results along with symptoms and what they find during the exam.

Sometimes, your vet will also suggest urine or blood tests to check kidney function and protein levels since Lyme disease can mess with the kidneys.

Test timing makes a difference. If you test your dog too soon after infection, the results might not catch antibodies yet. Your vet might recommend follow-up tests if symptoms change or new worries pop up.

Treatment for Lyme Disease in Dogs

If your dog gets diagnosed with Lyme disease, the main goal is to get rid of the infection and help them bounce back. Treatment almost always means antibiotics and some supportive care at home—or, in rare cases, a quick trip to the clinic.

Antibiotic Treatment Options

The go-to treatment for Lyme disease in dogs is antibiotic therapy. Most vets reach for doxycycline first, usually for at least 30 days. Sometimes, if symptoms are stubborn or severe, the course goes longer.

If doxycycline isn’t a fit, vets might choose amoxicillin or minocycline instead. These antibiotics target the Borrelia bacteria directly. Many dogs perk up within a day or two of starting meds, which is always a relief to see.

On rare occasions, if the infection is really bad or your dog becomes anaemic, a blood transfusion might be necessary. Still, most mild and moderate cases respond well to the right antibiotic treatment.

Supportive Care and Recovery

Supportive care is all about helping your dog feel better and heal up. Pain relievers like non-steroidal anti-inflammatory drugs (NSAIDs) can help with joint pain or swelling, but only use them if your vet gives the green light.

Make sure your dog gets plenty of rest and easy access to food and water. Skip the intense playtime for a bit and keep things low-key during recovery.

Watch for side effects from antibiotics, such as diarrhoea or loss of appetite, and let your vet know if anything seems off. Routine follow-up is important, too. Your vet might suggest repeat blood tests to see how things are going and make sure the infection’s truly gone.

With the right care, most dogs bounce back from Lyme disease and get back to their regular routines within a few weeks. That’s always good news. Lyme disease in dogs

Preventing Lyme Disease in Dogs

Prevention really comes down to stopping tick bites before they happen. You can seriously cut your dog’s risk by using proven tick control products and steering clear of tick-heavy spots.

Tick Control and Avoidance

Ticks are the main way Lyme disease gets to dogs. Use a tick prevention treatment your vet recommends. These come as spot-on liquids, chewable tablets, or collars—just follow the instructions for best results.

Check your dog’s fur and skin every day, especially after walks in grassy or wooded places. Run your hands over their body, paying special attention to the ears, neck, and between the toes. If you find a tick, remove it quickly using tick tweezers. Grab the tick close to the skin and pull it out steadily. Don’t twist, burn, or squeeze it.

Try to limit time in places where ticks like to hang out—fields, tall grass, thick woods, or piles of leaves. Keeping your yard tidy, mowing the lawn, and clearing out garden waste can help, too.

Strategies for Reducing Exposure

Planning your walks and playtimes can help dodge tick bites. Stick to paths, skip dense brush, and avoid long grass when you can. Wearing light-coloured clothing makes it easier to spot ticks on your dog and yourself.

If you live in or visit a tick-heavy area, ask your vet about a Lyme disease vaccine. The vaccine isn’t for every dog, but it can be a smart move for those at higher risk.

Wash your dog’s bedding and any camping gear regularly. After outdoor adventures, check yourself and your dog for ticks. Tick collars or sprays add another layer of protection, especially when ticks are most active.

Vaccination and Other Preventive Measures

Preventing Lyme disease in dogs takes both vaccination and solid tick control. Some breeds seem more likely to get really sick from Lyme disease, so they may need extra attention.

Lyme Vaccine Use in Dogs

The Lyme vaccine lowers your dog’s risk of getting sick after a bite from an infected tick. Vaccination is especially wise if you live in or travel to Lyme hot spots—think wooded areas or places with lots of deer.

Many vets recommend the vaccine as part of regular care in these risky areas. Dogs usually get two shots a few weeks apart, then a yearly booster to stay protected. The vaccine doesn’t block every case, though, so keep using tick preventives even if your dog’s vaccinated.

Other steps to take alongside vaccination:

• Use tick prevention products like spot-on treatments or tick collars
• Check your dog’s skin and fur for ticks after walks
• Keep your garden grass and shrubs trimmed

Combining vaccination with tick prevention gives your dog the best shot at staying healthy. If you’re curious, there’s more on why vaccination and tick prevention matter at Vetster’s page on Lyme disease, prevention, and treatment in dogs.

Role in At-Risk Breeds

Some breeds, like golden retrievers and labrador retrievers, face higher risks for severe Lyme disease. They can have stronger immune reactions, which sometimes lead to kidney trouble.

If you have one of these breeds, your vet will probably push harder for vaccination. It’s also important to stick with tick prevention all year.

Even if your dog isn’t a high-risk breed, any pup that spends time outside in tick areas can benefit from prevention. Always check your dog after walks, and ask your vet about vaccination if you’re in a Lyme-endemic spot. For more, see the VCA Animal Hospitals advice on Lyme disease.

Managing Tick Removal at Home

Pulling ticks off quickly and properly helps cut the risk of Lyme disease and other nasties. Using the right tool matters because the wrong method can leave tick bits behind or raise the chance of infection.

Safe Tick Removal Process

A proper tick removal tool or tick remover works best. Slide the tool under the tick, right up against your dog’s skin. Twist gently in one direction until the tick lets go. Don’t yank or squeeze—it can push germs into your dog.

Skip your fingers or regular tweezers, which might crush the tick. Don’t burn or put chemicals on it either; those tricks aren’t safe. After you get the tick out, check that the head came out, too, and clean the bite area.

Most pet shops sell easy tick removers, so it’s worth picking one up. For a step-by-step guide, check out how to remove a tick from a dog.

Co-Infections and Related Tick-Borne Diseases

Understanding Ehrlichiosis and Anaplasmosis

Ticks can spread several diseases to your dog at once. Ehrlichiosis and anaplasmosis are two common co-infections that show up alongside Lyme disease.

Ehrlichiosis comes from Ehrlichia bacteria. It often causes fever, appetite loss, and bruising. If left untreated, it can mess with your dog’s immune system and organs. Early diagnosis really helps, and antibiotics usually do the trick.

Anaplasmosis, caused by Anaplasma bacteria, brings fever, joint pain, and lethargy. Dogs can get super tired and limp around. Antibiotics help here, too. These diseases sometimes show up with other tick-borne illnesses, so vets often check for several infections if your dog gets sick after a tick bite.

Long-Term Outlook for Dogs with Lyme Disease

Most dogs with Lyme disease get better if treated early. But some dogs might deal with ongoing health problems, like repeat infections or lingering symptoms.

Chronic Illness and Recurrence

If you don’t catch Lyme disease early, your dog might end up with long-term problems. Some dogs deal with joint pain, stiffness, and swelling that lingers even after the infection clears.

Chronic Lyme can also make kidney issues more likely, especially for certain breeds. In rare cases, kidney failure develops and that can seriously hurt your dog’s health.

Dogs with chronic Lyme sometimes seem better for a while, but then their symptoms come back. Recurring issues mean you’ll need to keep a close eye and maybe return to the vet for more treatment.

Watch for limping, a drop in appetite, or just unusual tiredness. For more details on these long-term effects, check out the section on chronic Lyme disease in dogs.

Frequently Asked Questions

Lyme disease in dogs doesn’t always look the same from one pet to another. Sometimes, you won’t even spot clear signs right away.

Early diagnosis and treatment matter a lot for recovery and to avoid bigger health problems down the road.

What are the common symptoms to look out for in dogs with Lyme disease?

Common signs include lameness, a stiff walk, fever, and low energy. You might also notice joint swelling or your dog skipping meals.

Sometimes, symptoms don’t show up until months after a tick bite. If the kidneys get involved, you could see vomiting or weight loss. For more info, visit this page on Lyme disease symptoms in dogs.

What treatment options are available for Lyme disease in canines?

Most vets start with antibiotics, usually doxycycline. If your dog seems uncomfortable, pain relief might help too.

Treatment length depends on how bad the infection is, but most dogs perk up just a few days after starting meds. For more details, check this guide on Lyme disease in dogs.

Is there a possibility of completely curing Lyme disease in dogs?

Many dogs bounce back with quick, proper treatment and get back to normal. Some, though, might have lingering joint pain or other issues even after the infection is gone.

If you treat it early, a full cure is likely. But if kidney or joint damage happens, that can stick around for good.

How does Lyme disease affect the life expectancy of dogs?

Most dogs who get treated on time will have a normal life expectancy. If the disease hits the kidneys, though, it can cause kidney failure and shorten your dog’s life.
