Lyme Disease in Dogs: Tick Prevention & Symptoms

Finding a tick on your dog or cat can be alarming. While not every tick bite leads to illness, ticks can transmit serious diseases that affect pets throughout Massachusetts and Rhode Island.

The good news is that most tick-borne diseases are preventable. Understanding the risks, recognizing the signs of illness, and using year-round prevention can help keep your pet healthy.

Why Tick Prevention Matters in Massachusetts and Rhode Island

Massachusetts and Rhode Island are among the regions where Lyme disease and other tick-borne illnesses are commonly diagnosed in both people and pets. Ticks thrive in wooded areas, tall grass, leaf litter, parks, and even suburban backyards.

Many pet owners assume ticks are only active during the spring and summer months. Ticks can become active any time temperatures rise above freezing. Even mild winter days can create opportunities for exposure.

Because of this, veterinarians recommend year-round tick prevention for dogs and cats throughout New England.

What Diseases Can Ticks Transmit to Pets?

Ticks can carry and transmit several diseases that affect dogs and cats.

Lyme Disease

Lyme disease is caused by the bacterium Borrelia burgdorferi and is transmitted by the black-legged tick, also known as the deer tick.

Common signs of Lyme disease in dogs include:

Limping or shifting leg lameness

Joint pain and swelling

Fever

Lethargy

Decreased appetite

Reluctance to run, jump, or climb stairs

While cats can be exposed to Lyme disease, they rarely develop clinical illness.

Anaplasmosis

Anaplasmosis is another disease spread by deer ticks and can affect both dogs and cats.

Symptoms may include:

Fever

Lethargy

Joint pain

Decreased appetite

Vomiting

Difficulty walking

Ehrlichiosis

Ehrlichiosis is transmitted by several tick species and can cause:

Fever

Weight loss

Loss of appetite

Low platelet counts

Abnormal bruising or bleeding

Rocky Mountain Spotted Fever

Although less common in New England than Lyme disease, Rocky Mountain spotted fever can occur and may cause severe illness.

Symptoms can include:

Fever

Lethargy

Swollen joints

Neurologic signs

Abnormal bleeding

Should My Pet Be Tested After a Tick Bite?

Not necessarily.

A common misconception is that pets should be tested immediately after a tick is discovered. Most tick-borne disease tests detect antibodies produced by the immune system, and it can take several weeks after exposure for those antibodies to develop.

Testing immediately after a tick bite may produce a false-negative result.

If your veterinarian recommends testing, they may perform a 4Dx test, which screens for:

Lyme disease

Anaplasmosis

Ehrlichiosis

Heartworm disease

If a dog tests positive for Lyme exposure, additional testing may be recommended to evaluate kidney health and determine whether active disease is present. Call our ER with any question 508-730-1112.

Use Veterinary-Recommended Tick Preventatives

Several highly effective options are available, including:

Monthly oral medications

Long-acting oral chewables

Topical preventatives

Tick collars

Your veterinarian can help determine which option is best based on your pet’s age, lifestyle, and health history.

Perform Daily Tick Checks

After spending time outdoors, check your pet carefully, especially around:

The ears

Under the collar

Between the toes

The armpits

Around the tail

Under the chin

Removing ticks promptly can reduce the risk of disease transmission.

Maintain Your Yard

Simple landscaping changes can help reduce tick populations:

Keep grass trimmed short

Remove leaf litter

Clear brush and overgrowth

Create barriers between wooded areas and play spaces

Ask About the Lyme Vaccine

For many dogs in Massachusetts and Rhode Island, Lyme vaccination provides an additional layer of protection.

While no vaccine offers complete protection, vaccination combined with year-round tick prevention can significantly reduce risk.

Currently, there is no Lyme vaccine available for cats.

Important Safety Tip for Cat Owners

Never use a dog tick preventative on a cat.

Many canine products contain ingredients that are toxic to cats and can cause severe illness or death. Always use feline-specific products recommended by your veterinarian.

When Should I Call a Veterinarian?

Seek veterinary care promptly if your pet develops:

Severe lethargy

Fever

Swollen or painful joints

Difficulty walking

Refusal to eat for more than 24 hours

Pale gums

Labored breathing

Unexplained bruising or bleeding

These symptoms may indicate a serious tick-borne illness that requires medical attention. Book an appointment with our primary care hospital Coastal Veterinary Care today.
