Lyme disease is a bacterial infection caused by Borrelia burgdorferi and transmitted to dogs through the bite of an infected blacklegged (deer) tick. While it is one of the most common tick-borne illnesses in dogs, the good news is that 90 to 95% of infected dogs never show symptoms.
Can Yorkies Get Lyme Disease?
Yes, any dog can get Lyme disease if bitten by an infected tick. However, the disease is most prevalent in specific geographic regions including the northeastern United States, the upper Midwest, and parts of the UK and Europe. If you live in or travel to these areas with your Yorkie, prevention is essential.
Symptoms of Lyme Disease in Dogs
Symptoms typically appear 2 to 5 months after the tick bite. Unlike humans, dogs do not develop a “bullseye” rash. When a dog does become symptomatic, signs include:
- Shifting-leg lameness — Limping that moves from one leg to another as different joints become inflamed
- Swollen, painful joints — Stiffness and reluctance to walk, run, or jump
- High fever — Body temperature spiking above 103°F (39.5°C)
- Lethargy — A sudden drop in energy
- Loss of appetite — Refusing meals or eating significantly less
- Swollen lymph nodes — Particularly near the tick bite site
Treatment for Lyme Disease
A standard 30-day course of doxycycline is the frontline treatment. Most dogs show dramatic improvement in joint pain and fever within 24 to 48 hours. It is essential to complete the full course to prevent recurrence. Anti-inflammatory medications may also be prescribed for joint discomfort.
Asymptomatic dogs that test positive are not usually treated with antibiotics. Your vet will instead recommend periodic urine checks to monitor kidney function, as Lyme nephritis (kidney inflammation) is a rare but serious complication.
Preventing Lyme Disease in Yorkies
A tick must be attached for 24 to 48 hours to transmit Lyme bacteria. Prevention focuses on killing or repelling ticks before they can transmit the disease:
- Monthly tick prevention — Oral chews like NexGard or Simparica, or topicals like Frontline Plus, are highly effective
- Check for ticks daily — Especially in the paws, between toes, inside ears, and under the tail
- The Lyme vaccine — Available for dogs in high-risk areas. Ask your vet if your Yorkie’s lifestyle warrants it.
- Yard maintenance — Keep grass short, clear leaf piles, and trim brush to reduce tick habitat
