Tick Borne Diseases In Dogs

If your dog is an enthusiastic and frequent hiking or camping companion, you should be aware of the array of diseases that ticks can transmit to your furry friend. Why are ticks so bad for dogs ? When many people think of tick borne diseases in dogs, their thoughts are dominated by the detriments of Lyme disease.

Tick Borne Diseases In Dogs

Lyme Disease

Lyme disease originated in the town of Lyme, Connecticut, for which the disease was named. It is transmitted by deer ticks and western blacklegged ticks, and its incidence has spread throughout the northeastern region of the United States.

Transmitted by the brown dog tick, bartonellosis presents with symptoms that are intermittent and include:

  • Fever
  • Limping

All of the above-mentioned tick borne diseases in dogs are treated with broad-spectrum antibiotic therapy. The best outcome is achieved when the illness is diagnosed and treated as early as possible. Consider having your dog screened for tick-borne diseases as part of its annual veterinary checkup.

Tick Bite Symptoms

Not every tick bite results in a tick borne disease. If a tick has bitten your dog, you may observe these tick bite symptoms :

  • A small lump at the site of the bite
  • Redness of the skin on the site of the bite
  • Limping or joint swelling if the dog was bitten on one of its limbs

Prevention is Prudent

While some of the above-mentioned diseases can be treated, they can have adverse residual effects on your pet’s health. You must also be aware that many tick borne diseases also afflict humans. Take the following precautions to provide your dog with the best protection against tick borne diseases before you hit the campgrounds and hiking trails together.

  • Talk to your veterinarian about vaccinating your dog with the Lyme disease vaccine.
  • Use a tick preventative product that is prescribed by your veterinarian on your dog.
  • Conclude each day of hiking or camping by checking your dog thoroughly for ticks. If you reside in a heavily wooded area where ticks are prevalent, check your dog every evening after it is indoors for the night.
  • If you find an embedded tick, carefully remove it. Your veterinarian can show you how to accomplish this effectively. If you are not confident that you successfully removed the entire tick, bring your dog to your veterinarian as soon as possible. Learn here how to remove a tick from a dog.

By being proactive in protecting your dog against tick borne diseases, you and your furry companion can safely enjoy exploring nature together for many seasons to come.
