Summer is for long walks, garden lounging, and outdoor adventures with your dog. Well, warmer weather brings a lot of fun but also comes with some important invisible threats to run — each dog parent should know in advance. Knowing what to watch for — and how to nip issues in bud before the problems begin — can let you enjoy the sunshine and keep your dog safe, comfortable, and happy.
Here are 12 common summer hazards for dogs and what you can do to avoid them:
1. Heatstroke
Dogs struggle to regulate their body temperature, which makes them especially vulnerable in hot weather. Excessive panting, drooling, lethargy, bright red gums, vomiting, or collapse are all warning signs.
If you suspect heatstroke:
Move your dog to a cool, shaded area
Offer cool (not icy) water
Contact your vet immediately
Never leave your dog in a parked car — even for a few minutes.
2. Dehydration
Hot days increase your dog’s need for water. Signs of dehydration include dry gums, sunken eyes, thick saliva, lethargy, and reduced appetite.
Always ensure fresh water is available, especially during walks or playtime. You can also encourage drinking with dog-safe bone broth or hydrating frozen treats.
3. Sunburn
Yes — dogs can get sunburn too. Pale, short-coated dogs are especially at risk, with ears, noses, and bellies being common trouble spots.
Protect your dog with shade, limited sun exposure during peak hours, and dog-safe sunscreen where needed.
4. Hot Pavements
Pavements heat up faster than the air temperature and can burn sensitive paws. If you can’t hold the back of your hand on the ground for seven seconds, it’s too hot for your dog.
Walk early morning or evening, stick to grass where possible, and avoid long pavement routes in heat.
5. Toxic Plants, Grass Seeds & Foxtails
Many summer plants are toxic to dogs, while grass seeds and foxtails can embed into skin, ears, paws, or noses — causing painful infections.
Check your dog after walks and contact your vet if you notice swelling, limping, excessive licking, or abscesses.
6. Insects & Parasites
Bees, wasps, mosquitoes, ticks, and fleas are all more active in summer. Stings can cause swelling or allergic reactions, while parasites may transmit disease.
Keep parasite prevention up to date and avoid long grass where possible.
7. Compost Bins
Compost may smell irresistible to dogs, but it can contain mould and toxins that cause serious poisoning. Symptoms include vomiting, tremors, seizures, and agitation.
Always secure compost bins and keep dogs well away.
8. Overexertion
Dogs don’t always know when to stop. Heavy panting, reluctance to move, drooling, vomiting, or weakness may signal overexertion.
Shorter walks, plenty of breaks, and shade are key during warm weather.
9. Beach Hazards
Sand, shells, saltwater, and sharp debris can all cause problems. Saltwater poisoning and intestinal blockages are real risks.
Bring fresh drinking water, supervise closely, and discourage scavenging.
10. Blue-Green Algae
This toxic bacteria appears as green or blue scum on lakes, ponds, and rivers during hot weather. Ingesting or swimming in contaminated water can be fatal.
If you see algae — avoid the water entirely.
11. Snakes & Wildlife
Adders, hedgehogs, slugs, and snails can all pose risks. Bites, spikes, or parasites like lungworm may require urgent vet treatment.
Keep your dog under control and up to date with worming treatments.
12. Campfires & BBQs
Hot coals, skewers, and charcoal are dangerous if ingested or touched. Burns and internal injuries are common summer emergencies.
Keep dogs at a safe distance and offer a long-lasting chew to keep them occupied.
Final Thoughts
Summer should be fun for you and your dog — but, knowing that, it can be. Picking the right course knowing what risks come your way, and preparing beforehand, can guard your dog, avoidable risks — and enjoy all the things that season brings.
