About lyme disease in dogs

Lyme Disease in dogs can cause serious health problems if it`s not diagnosed and treated early.

Lyme Disease is also known as Borreliosis, and is carried and transmitted by ticks (usually the tiny Deer Tick, aka the `Black Legged Tick`), and is most often found in the north-eastern United States.

Luckily there is a simple way to protect your pooch from being infected, plus there`s also a vaccine available for dogs who are at `high risk` of contracting the infection.

Here`s what you need to know about Lyme Disease in dogs......

How is Lyme Disease in Dogs Transmitted

Lyme Disease is a vector-born disease. This means it is an infection disease which is transmitted by another living organism, in this case the teeny-weeny Deer Tick.

Deer Ticks (aka Black Legged Ticks) primary host are deer, but these little critters aren`t picky, and ifyour dog (or you) happen to wander through long grass or wooded areas, then they will happily `jump aboard`!

Lyme Diseaseisn`t `contagious` and you can`t catch it from your dog, however if aninfected Deer Tick bites you then you can be infected in the same way as Fido.

Humans tend to suffer from flu-like symptoms, including achyjoints and swollen lymph nodes, and a characteristic `bullseye` rasharound the area of the original tick bite.

This diseasecan occur in almost any part of the US. Recent studies show Lyme Disease carrying ticks in 37 states and Lyme Disease cases in humans has tripled in the last 20 years!

However, it is significantly more prevalent in certainareas, particularly the north-eastern states.

The `high risk` Eastern states for infection include:

• Massachusetts
• Minnesota
• North Dakota
• New York State
• Pennsylvania
• Virginia
• Wisconsin

This region is home to the Eastern Blacklegged Tick (aka Ioxdes Scapularis).

Although there are many fewer cases on the East Coast, California and Arizona are also states where there is a slightly elevated risk for Lyme Disease.

The west coast is home to the Western Black Legged Tick (aka Ioxdes Pacificus).

Not all dogs who are bitten by infected ticks will get sick, and not all deer ticks are carrying Lyme Disease.

Studies have shown that a large percentage of dogs already have some immunity, but there`s no way for you to tell by looking whether or not your dog is at risk.

It`s best to follow preventative measures, and also treat any tick found on your dog as a potential threat (there are also other tick-borne diseases such as Rocky Mountain Spotted Fever, Ehrlichiosis and others to be concerned about).

Deer ticks are actually quite small, usually between 2 to 3.5 mm, and a fully grown adult is no bigger than a sesame seed. When it is sucking blood however, it grows considerably in size and is easier to see.

Nasty isn`t it!

Symptoms Of Lyme Disease In Dogs

The symptoms of canine Lyme Disease usually appear somewhere between 2and 5 months after infection has taken place.

So atfirst your dog won`t have any symptoms at all.

But occasionallythey can appear sooner (in as little as a few weeks) or sometimes evenlater, possibly up to a year or longer after exposure.

It`s also important to realize that the symptoms of lyme disease in dogs are usually NOT the same as the symptoms you might see in a human.

You are very unlikely to see that classic `bullseye rash` for example, but occasionally you might.

The most common symptoms of this Lyme Disease in dogs are :

• Limping or lameness - most often seen in one of the front legs, but can affect any leg/s, and can be intermittent. General stiffness or arthritis-like symptoms.


• Swollen or tender joints - a result of inflammation, usually worse in the leg that is most severely affected but becoming generalized in time


• Swollen lymph nodes - a reaction to the bacteria in the dogs system


• Fever - a fever, usually somewhere between 103 and 105


• Lethargy- this can be a result of the fever and a general feeling of beingunwell, but a reluctance to walk, or even move, can also be a directresult of the painful joints seen in canine Lyme Disease


• Loss of appetite - again due to the fact that your pet isn`t feeling well. Sustained reluctance to eat can cause significant weight loss.

Rare, but serious, symptoms which might appear include:

• Heart irregularities
• Kidney problems
• Neurological/nervous system issues

Themost important symptoms to be aware of are limping or lameness, swollenjoints and/or lymph nodes, and fever.

Lethargy and loss of appetite aremore general signs of illness, and could more easily be symptoms ofmany other illnesses or diseases.

It`salso important to know that the `bulls-eye` rash that is often seen as asymptom of Lyme Disease in humans, is much less commonly seen in dogs.

If the tick bite was on a relatively hair-free area of your dog (ie his belly, inner hind leg etc.), then you maysee a red, bullseye type rash around the bite itself.

However, mostdogs don`t develop this symptom, and even if they do the chances arefairly good that it will be hidden by his fur.

If left untreated, Lyme Disease in dogs can cause some very serious health issues including :

• Kidney damage or kidney failure


• Heart problems


• Neurological problems including seizures


• Chronic joint inflammation/arthritis


• Immune system problems

So,it`s clear how important it is to take your dog to the vet if you havethe slightest suspicion that your dog could be at risk.

Treating Canine Lyme Disease

Treatments for this disease are usually very effective, if the illness is recognized early enough.

Ifyour pup or dog is showing any of the signs/symptoms above, get himveterinary attention immediately as they can progress very quickly.

Your dog could go from having a slight limp, to being almost immobilewithin a couple of days.

Anytime your dog is in a wooded area, orin long grass, he is exposed to ticks.

If you live in the countryside,he could even pick them up in his own yard.

It`s vital to check your dogdaily and if you find a tick (or several ticks), remove them rightaway.

Because of that 18 - 48 hour `window` before an infected tickcan transmit the disease, being vigilantabout checking for (and removing) ticks is the best way to prevent Fido from getting sick.

If your puppy has already picked up a tick and is not yet on any preventativemedications you need to remove it as quickly as possible.

Getting it off your puppy within 24 hours can really reduce thechances of it being able to transmit any diseases.

• Never touch a tick with your bare hands as Lyme Disease can be transmitted through your skin. Put on rubber/latex gloves first.
• For the fastest, easiest, most fool-proof tick removal I highly recommend either Dr. Mercola`s Tick Stick Kit or the Tick Twister Set. They work great and make it a snap to remove small or large ticks (there are also many other similar products, pick whichever one you think will work best for you). 

• Until you get your Tick Stick or Tick Twister, you can use a pair of tweezers or forceps instead.

  Grasp the tick`s headfirmly, as close to your pup`s skin as possible. Pull slowly but firmly. Don`t grip the tick around it`s swollen body orsqueeze it`s body.

• Once the whole tick is out, use a disinfectant orrubbing alcohol to clean the area (and your gloves/tweezers etc. too),then apply a little anti-biotic ointment to the area of the bite.

• When you`re removing a tick from your dog, if it`s head is left under your dog`s skin it could become infected, sokeep an extra-close eye on the area for the next few days.

• Don`t forget to make sure you kill the tick before disposing of it or you may see it again!

• Once you`ve done all that, be sure to get Fifi on a regularschedule of flea and tick medication so you don`t have to do the samething all over again.

The more common American Dog Tick isn`t a carrier, but most of us can`t really tell the difference between tick species..... and I know that I`m not too keen to get up really close to these nasty little creatures if I can help it!

The most commonly used antibiotics used for treating Lyme Disease in dogs are Doxycycline and Amoxicillin.

The earlier the antibiotics are started, the better the chance that your dog will make a full recovery.

As symptoms don`t show for weeks, this early warning can allow you to set up treatment much earlier than would otherwise be possible, saving a lot of discomfort, pain, distress and cost.

There is an additional cost of $39.95 to have the tick analyzed, but to my mind it`s well worth the money - especially if you`re in a high risk state.

A three week course of these antibiotics is the minimum most veterinarians recommend, and it may be necessary for your dog to take them for a month, or occasionally even longer.

If the antibiotics are stopped too early, symptoms may come back (along with the risk of the long-term damage listed above).

Preventing Canine Lyme Disease

Rule #1 - Use an effective tick preventative, regularly!

Rule #2 - If you see a tick on your dog, remove it right away!

Luckily, given the potential severity of the effects of canine Lyme Disease, preventing this illness is fairly simple.

Using an effective tick preventative on a regular basis will protect your dog fairly effectively, by ensuring that any ticks on him will die within the 18 hour `window` before infection sets in.

Over the counter products can`t be relied on, and it`s important to choose a product that contains Permethrin or Amitraz. 

The most popular brands of topical treatments such as Frontline Plus or Advantix II are good choices.

Some collars such as the Preventic Tick Collar or a Seresto Tick Collar canalso be used, but as these may not be as effective as the topicaltreatments.

It"s a good idea to use them as extra protection if ticks arereally bad in your area, or if your dog spends a lot of time outhunting/walking in long grass or wooded areas.

A Preventic collar can beused at the same time as the topical treatments, but is effective forup to 3 months.

If you live in an area where Lyme Disease is prevalent, you may want to consider having your pup vaccinated against it.

Although not 100% effective (no vaccine is!), it"s still the best way to protect a high-risk dog.
