Summer exposes dogs to numerous outdoor dangers
With fine weather, walks become longer and dogs spend more time outdoors. However, this period also increases the risks to their health. Dry grasses, external parasites and certain caterpillars can cause sometimes serious complications.
The dangers of summer for dogs mainly concern:
- Grass seeds
- Ticks
- Pine processionary caterpillars
- Heatstroke
- Skin irritations
- Paw pad injuries
Some dogs are even more sensitive:
- Long-haired dogs
- Very active dogs
- Puppies
- Dogs living in the countryside
- Hunting dogs
Daily monitoring therefore remains essential throughout the summer season.
Grass seeds in dogs: a common danger in summer
Why are grass seeds dangerous?
Grass seeds are small dry spikes found in tall grass. Their pointed shape allows them to easily catch onto a dog's coat. They then work their way into the skin or certain orifices.
The most affected areas are:
- The ears
- The eyes
- The nostrils
- The spaces between the toes
- The genital area
A grass seed can quickly cause:
- Significant pain
- An abscess
- An infection
- A perforated eardrum
Symptoms of a grass seed in dogs
Several signs should raise concern:
- The dog shakes its head vigorously
- It sneezes suddenly
- It licks a paw excessively
- It keeps one eye closed
- It suddenly limps
In this case, a veterinarian should be consulted quickly. The longer the grass seed stays, the deeper it migrates.
How to prevent grass seeds?
Prevention remains the best solution.
Here are the right habits:
- Avoid tall, dry grass
- Inspect the dog after each walk
- Brush the coat regularly
- Trim the hair between the pads lightly if needed
To clean small irritations after a walk, you can use:
- Veterinary cleansing wipes
- An antiseptic spray suitable for dogs
- A mild disinfectant solution

Ticks in dogs: watch out for vector-borne diseases
Why do ticks pose a real danger?
Ticks are very present from spring until autumn. They attach themselves to a dog's skin to feed on blood.
The problem does not come only from the bite. Indeed, ticks can transmit several serious diseases:
- Babesiosis
- Lyme disease
- Ehrlichiosis
Some infections can cause:
- Severe fatigue
- Fever
- Loss of appetite
- Blood disorders
Where are ticks found?
Ticks live mainly:
- In tall grass
- Forests
- Gardens
- Damp areas
Even a dog living in the city can be affected.
Recommended antiparasitic solutions
To effectively protect your dog, it is important to use an antiparasitic suited to its weight and lifestyle.
Several solutions exist:
- Spot-on pipettes
- Antiparasitic tablets
- Antiparasitic collars
- Repellent sprays
Ideally, the dog should be treated before major periods of exposure.
How to remove a tick correctly?
A suitable tick removal hook should be used. Then:
- Slide the hook under the tick
- Turn gently
- Disinfect the area
Never pull abruptly or use alcohol before removal.
Pine processionary caterpillars: a sometimes life-threatening danger
Why are pine processionary caterpillars so dangerous?
Pine processionary caterpillars have extremely toxic urticating hairs. A simple contact can cause a severe reaction in dogs.
Dogs are often contaminated when they sniff or lick a caterpillar during a walk.
Symptoms after contact with a pine processionary caterpillar
Signs appear very quickly:
- Hypersalivation
- Swelling of the tongue
- Intense pain
- Vomiting
- Breathing difficulties
In severe cases, part of the tongue can become necrotic.
What to do in an emergency?
Action must be taken immediately:
- Rinse the mouth thoroughly with lukewarm water
- Wear gloves
- Avoid rubbing
- Consult a veterinarian urgently
Every minute counts.
How to avoid pine processionary caterpillars?
To limit the risks:
- Avoid areas infested with pine trees
- Keep your dog on a leash
- Watch for nests in trees
- Report contaminated areas

Frequently asked questions about summer dangers for dogs
How do I know if my dog has a grass seed?
A dog affected by a grass seed often shows sudden discomfort: limping, repeated sneezing, head shaking or excessive licking. A quick consultation helps avoid complications.
Are ticks dangerous even if they stay attached for a short time?
Yes. Some diseases can be transmitted quickly after the bite. The longer the tick stays attached, the higher the risk. It is therefore necessary to inspect your dog after every outing.
Can a pine processionary caterpillar kill a dog?
Yes, in certain severe cases. Inflammatory reactions can cause severe respiratory distress. Immediate veterinary care remains essential.
Which antiparasitic should I choose for summer?
The choice depends on the dog's weight, its environment and its level of exposure. A dog living in the countryside or often going into forests generally needs enhanced protection.
