Tick-borne diseases can put your dog’s health in jeopardy — and are also a danger for people. These conditions can have painful symptoms and even turn life-threatening for your pooch. In this post, our the Pacific Northwest vets list some common tick borne illnesses in dogs and which symptoms to watch for.
Tick-Borne Illness in Dogs
Thousands of dogs across the United States are afflicted with tick borne illnesses every year. These are capable of leading to some very serious and painful symptoms for your pet. Some conditions spread via ticks can even be fatal for dogs.
How Tick-Borne Diseases Attack Your Dog’s Immune System
With a single bite, ticks can transmit a single type of organism or multiple organisms to your dog (confection). This allows different organisms to work tother to release toxins and trigger your dog’s immune system.
Once these organisms are in the body, they can invade your pooch’s cells and hijack their immune system. Some tick-borne organisms even help one another survive inside your dog’s body, which can lead to recurring or chronic infections.
Your dog’s tissues and organs can become infected and inflamed as a result of illnesses spread by ticks. This can lead to numerous symptoms. In some cases, your dog may not display symptoms until several weeks after he or she has become infected with disease.
Common Tick-Borne Diseases Seen in Dogs
Across North America, many tick-borne diseases in dogs are contracted near the home. In other cases, the pet has contracted these diseases while away from home (for example, while on out-of-state camping trips with their owner). These are some of the most common tick-borne diseases diagnosed in dogs in the Pacific Northwest.
Lyme disease is seen in dogs across North America and is caused by the Borrelia burgdorferi bacteria, which is transmitted by infected deer ticks or black-legged ticks. Symptoms of Lyme disease in dogs may include joint pain or swelling, enlargement of lymph nodes, fever, lethargy and lameness. The disease can be successfully treated.
While Canine Bartonellosis is less common than some other tick-borne diseases seen in dogs, this disease can have very serious symptoms. Some early signs of Canine Bartonellosis include intermittent fever and lameness. However, left untreated this disease can lead to serious conditions such as heart or liver disease.
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 be very 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.
There are a number of different ticks that 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.
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.
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 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.
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
Dogs diagnosed with tick-borne illnesses are typically treated with broad-spectrum antibiotics. While your dog is undergoing treatment with antibiotics your vet may also recommend giving your pup probiotics to prevent gastrointestinal issues.
Recurring tick-borne conditions can be challenging to beat. Even after your dog appears to have recovered, regular blood work may be necessary in order to detect recurrences as early as possible.
Protecting Your Dog Against Tick-Borne Diseases
Year-round tick prevention medications are 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, be sure to inspect 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 to learn what ticks in your area look like and where they are typically found.
Ticks need to be removed carefully to protect your pup's health. Contact your vet for instructions on how to properly remove ticks from your dog's skin.
