Symptoms caused by tick-borne illnesses can be painful and even life-threatening for your dog. Here, we outline some of the most common tick-borne diseases in dogs, and the symptoms to watch for.
Those Pesky Ticks Are Everywhere!
Tick-borne diseases negatively impact the health of countless people and dogs in Mamaroneck and across the US, Canada and the world. These conditions can lead to very serious and painful symptoms, and some tick-borne diseases can even be life-threatening for dogs.
How Tick-Borne Diseases Attack Your Dog’s Immune System
Ticks transfer organisms when they latch on to your dog and begin to feed. In some cases, ticks will transfer a single organism but in many cases, ticks transfer two or more leading to coinfection. Once these organisms have found their way into your dog they invade your dog's cells and attack the immune system. Some tick-borne organisms are even capable of helping each other to survive inside your pet's body, which can lead to recurring or chronic infections.
Tick-borne illnesses result in your dog's organs and tissues becoming infected and inflamed, producing a range of symptoms. In some cases, symptoms may not appear until several weeks after your pet has become infected with the disease.
Common Tick-Borne Diseases Seen in Dogs
There are a number of tick-borne illnesses seen in dogs across North America. In some cases these diseases are spread by ticks that dogs encounter near home, in other cases, tick-borne diseases have been contracted by the pet while away from home (often while on out-of-state camping trips with their owners).
Below are some of the most common tick-borne diseases diagnosed in the Mamaroneck area.
Lyme Disease
Caused by the Borrelia burgdorferi bacteria transmitted by infected black-legged ticks or deer ticks, Lyme disease is seen in dogs and people across North America. In dogs, Lyme disease symptoms can include lethargy, lameness, fever, joint pain or swelling, and the enlargement of lymph nodes. Lyme disease in dogs can be successfully treated if diagnosed early.Canine Bartonellosis
Although Canine Bartonellosis is less common than some other tick-borne diseases we see in dogs, the symptoms of this disease can be very serious. Some of the earliest signs of Canine Bartonellosis include intermittent fever and lameness but left untreated this condition can lead to serious conditions such as heart or liver disease.Rickettsial Diseases
Rickettsial organisms are bacterial obligate intracellular parasites that can be spread by infected ticks. Rickettsial bacteria can cause a number of illnesses in dogs including Rocky Mountain Spotted Fever, Ehrlichiosis and Canine Anaplasmosis. Bacterial diseases such as those listed below can often be challenging to diagnose. Multiple tests or rounds of treatment may be needed before a definitive diagnosis can be determined for your dog's symptoms.Rocky Mountain Spotted Fever
RMSF or Rocky Mountain Spotted Fever is carried by the Rocky Mountain wood tick, brown deer tick and American dog tick. This tick-borne condition can be seen in dogs across Central, South, and North America, and can also affect humans. Swollen lymph nodes, joint pain, poor appetite, and fever are some of the most common symptoms of Rocky Mountain Spotted Fever in dogs. In some cases, dogs may also experience neurological symptoms such as balance issues or weakness.Canine Ehrlichiosis
Various tick species can transmit Canine Ehrlichiosis, including the American dog tick, brown dog tick and the lone star tick. Symptoms of this condition typically begin to appear about 1 -3 weeks after your dog has been infected and may include fever, poor appetite, nose bleeds, and bruising. Early diagnosis and treatment are the keys to the successful treatment of Canine Ehrlichiosis. Treatment can be more challenging in dogs that develop chronic symptoms of the disease.Canine Anaplasmosis
The most common symptoms of Canine Anaplasmosis are much the same as other tick-borne diseases and include lethargy, loss of appetite, stiff joints, fever, diarrhea, and vomiting. In severe cases, however, Canine Anaplasmosis can lead to seizures in dogs.Protozoal Diseases
Also transmitted by ticks are Protozoal intracellular parasites. These organisms make their home in the dog’s red blood cells are the cause of the Protozoal diseases listed below.Canine Babesiosis
Canine Babesiosis is primarily spread through the bite of infected brown dog ticks or American dog ticks. However, this condition can also be spread through the bite of an infected dog, contaminated IV blood or transferred from a pregnant mother to her unborn puppies through transplacental transmission. Canine Babesiosis causes the breakdown of red blood cells, resulting in symptoms such as jaundice, pale gums, lethargy, dark-colored urine, and in some cases generalized weakness and vomiting.Canine Hepatozoonosis
Although Canine Hepatozoonosis is a tick-borne disease, your pet could contract the disease by eating another infected animal such as a rodent or bird. Dogs infected with this disease will often show mild symptoms or no symptoms at all. That said, depending on the strain of the disease more severe cases can lead to symptoms that can seriously impact your pet's mobility such as muscle, bone, and/or joint pain. Other symptoms of Canine Hepatozoonosis include fever, pale gums and skin, and enlarged lymph nodes.Treatment for Tick-Borne Disease in Dogs
Broad-spectrum antibiotics are typically the number one treatment for dogs diagnosed with tick-borne illnesses. While your dog is undergoing antibiotic treatment your veterinarian may also recommend giving your pup probiotics to prevent gastrointestinal issues.
Recurring tick-borne conditions can be challenging to eliminate. Even after your dog appears to have recovered, regular blood work may be required to detect recurrences as early as possible.
Protecting Your Dog Against Tick-Borne Diseases
In many states, ticks are active year-round. The greatest risk of contracting a tick-borne disease is in the spring and early summer. Protecting your dog with tick control medications all year long is the number one defense against tick-borne diseases in dogs.
Speak to your vet to find out which parasite prevention medication is best for your pet based on where you live, your pet's age, and your dog's lifestyle.
While these medications go a long way to protecting your dog, no tick prevention method is 100% effective, so diligence is always a must.
If your dog has been in areas where ticks are known to live such as farmland, forests, or areas with tall grass, take the time to check your dog's skin for ticks as soon as you get home. Most ticks are dark brown or black in color and fairly large once they have begun to feed. An online search should help you learn what ticks in your area look like and where they are typically found.
Ticks should be carefully removed right away to reduce the risk of transmission and to help protect your dog's health. Contact your vet for instructions on how to safely remove ticks and prevent the spread of disease.
