Summer hazards: algae, snakes, stings and grass seeds

Toxic algae, snake bites, stings and grass awns are classic summer emergencies. Know the signs.

Toxic algae

In warm, still water, blue-green algae can form a green or blue-green scum along the shore. Their toxins can kill a dog within hours of swimming in or drinking the water, or of licking its coat afterwards. Stay away from discoloured water, rinse the dog with clean water after swimming and go to a vet at once if it vomits, drools, staggers or has seizures.

Snake bites and stings

A venomous snake bite usually hits the face or a leg, which swells quickly. Keep the dog calm, carry it if you can and go straight to a vet; do not cut, suck or tie off the bite. A wasp or bee sting usually causes only local swelling, but a sting in the mouth or throat, a swollen face or difficulty breathing needs a vet immediately.

Grass awns

Barbed grass seeds work their way into ears, between toes, up the nose or into the eyes, and can travel deep under the skin. Sudden head shaking, sneezing, licking a paw or squinting after a walk in dry grass are typical signs. Check the coat after walks and let the vet remove anything you cannot easily reach.

Test yourself: Summer hazards

Which water is most risky for toxic algae?
  1. Clear, fast-flowing stream water
  2. Warm, still water with a green or blue-green scum
  3. Salt water at a windy beach

Correct answer: Warm, still water with a green or blue-green scum

Blue-green algae thrive in warm, still water and can form a scum along the shore.

Your dog has been bitten by a snake. What should you do?
  1. Cut the wound and suck out the venom
  2. Tie a tight band above the bite
  3. Keep the dog calm and go straight to a vet

Correct answer: Keep the dog calm and go straight to a vet

Keep the dog as still as possible and get to a vet; cutting, sucking or tying off makes things worse.

When does a wasp sting need a vet immediately?
  1. When it is in the mouth or throat, or the dog has trouble breathing
  2. Whenever there is any swelling at all
  3. Never, stings are always harmless

Correct answer: When it is in the mouth or throat, or the dog has trouble breathing

Stings in the mouth or throat, a swollen face or breathing problems can block the airway.

After a walk in dry grass your dog suddenly shakes its head. What could it be?
  1. A grass awn in the ear
  2. Normal tiredness
  3. Too much water in the coat

Correct answer: A grass awn in the ear

Barbed grass seeds often end up in the ear canal and need to be removed by a vet.
