Dog Tick Bite: What to Do, Symptoms to Watch For, and When to Call a Vet

What to Do Right After You Find a Tick on Your Dog

Discovering a tick on your dog requires calm, prompt action. The most important thing is to remove the tick as quickly as possible — disease transmission risk increases significantly the longer a tick is attached, particularly after 24–48 hours of feeding.

Before removal:

• Part the fur to fully expose the tick and the bite site
• Note the tick's appearance (color, size, whether it is engorged) — this can help identify the species
• Gather your removal tools before you start

How to Safely Remove a Tick from Your Dog

The correct removal technique matters. Improper removal can cause the tick to regurgitate into the wound, increasing disease transmission risk.

What to use: Fine-tipped tweezers or a purpose-made tick removal tool (tick key, tick twister). These are available at most pet stores.

Step-by-step removal:

1. Grasp the tick as close to your dog's skin surface as possible
2. Pull upward with steady, even pressure — no twisting, jerking, or squeezing
3. Once removed, clean the bite site with rubbing alcohol or soap and water
4. Dispose of the tick in alcohol, a sealed bag, or by flushing — do not crush it with your fingers
5. Consider saving the tick in a sealed container in case your vet needs to identify it later

What not to do: Do not use petroleum jelly, nail polish, match flames, or other "suffocation" methods. These cause the tick to regurgitate saliva and can increase disease transmission risk.

Tick-Borne Diseases That Affect Dogs

The US is home to several tick species that can transmit diseases to dogs:

• Lyme disease (Borrelia burgdorferi): Transmitted by deer ticks (black-legged ticks). Most common in the northeastern US and upper Midwest. Can cause fever, joint pain, limping, and kidney disease in chronic cases.
• Rocky Mountain spotted fever (Rickettsia rickettsii): Transmitted by American dog ticks and Rocky Mountain wood ticks. Can be severe and potentially life-threatening if untreated.
• Ehrlichiosis: Transmitted by the lone star tick and brown dog tick. Causes fever, lethargy, and blood cell abnormalities.
• Anaplasmosis: Transmitted by deer ticks. Symptoms overlap with Lyme disease.
• Babesiosis: Transmitted by brown dog ticks. Destroys red blood cells and can cause anemia.

Symptoms of Tick-Borne Illness in Dogs

Symptoms can appear days to months after a tick bite and vary by disease:

• Fever (your dog's normal temperature is 101–102.5°F)
• Lethargy or unusual tiredness
• Loss of appetite
• Limping or joint swelling
• Swollen lymph nodes
• Vomiting or diarrhea
• Difficulty breathing (in severe cases)
• Pale gums (indicating anemia)
• Neurological signs such as incoordination or seizures (in severe cases)

When to Call the Vet

Contact your veterinarian if:

• You cannot fully remove the tick or the head remains embedded
• The bite site becomes red, swollen, or develops a bull's-eye pattern
• Your dog develops any of the symptoms above in the weeks following the bite
• The tick appeared engorged (indicating prolonged attachment)
• Your dog is a puppy, senior, or has underlying health conditions

Your vet can run blood panels to screen for tick-borne diseases (often included in annual heartworm tests as the 4Dx panel) and prescribe antibiotics like doxycycline if infection is confirmed.

Preventing Tick Bites in Dogs

Prevention is far easier than treatment. Effective prevention includes:

• Monthly tick prevention products (oral, topical, or collar-based) — speak to your vet about which is appropriate for your dog's lifestyle and region
• Checking your dog thoroughly after every outdoor excursion, particularly through wooded or grassy areas
• Keeping grass short in your yard
• Lyme disease vaccination (available and recommended in high-risk areas)

Your dog's wellbeing directly affects your own mental health. If the stress of managing your pet's health is affecting you, and you have a mental health condition, your pet may qualify as an emotional support animal — learn how an ESA letter from The Supportive Pet can protect your housing rights.
