What Hazards Should You Watch for With Pets in Spring?

Spring brings grass seeds that work into paws and ears, bulbs that dogs dig up, lilies in Easter and Mother's Day bouquets that are dangerous to cats, fleas and ticks waking up, chocolate eggs at nose height, and nesting wildlife in the yard. A little awareness covers most of it, plus knowing when to call the vet.
In the Southern Hemisphere, spring runs from about September to November.

What changes in spring, in brief.

Grass Seeds Travel Inward

Spring growth means seed heads ride home in fur, between toes and in ears. Grass awns are shaped to move one way only, forward, so a seed that looked harmless can work deeper over the following days. Dogs with feathery feet, floppy ears or dense coats pick up the most.

Check paws, ears and coat after any walk through long grass. Sudden limping, constant head-shaking or repeated sneezing straight after a walk can mean a seed has gone in: that is a same-day vet visit, not a job to dig at yourself.

Bulbs and Lilies

Daffodils, tulips and hyacinths going into loose soil look like an invitation to a dog that likes digging, and the bulbs can make pets ill if chewed. Fence new beds while they establish, or plant where a dog can't reach. If your dog has eaten a bulb, call your vet straight away.

Lilies are a special danger to cats. True lilies and daylilies are highly toxic to cats; even pollen licked off fur or water from the vase can cause serious kidney harm. Spring bouquets often include them, so keep them out of any home with a cat, and call your vet at once if a cat may have touched one.

Flea and Tick Season, and Easter

Warmer weeks bring fleas and ticks back to life, so spring is a good time to check your prevention plan hasn't lapsed. What your pet needs depends on where you live.

Flea, tick and worming treatments: see your vet or a pet supply store with trained staff. Never use a dog product on a cat.

Easter brings chocolate eggs, baskets and baking at nose height for a few busy weeks. Our toxic foods guide covers what is dangerous.

A Spring Kit

A slicker brush or fine comb makes the after-walk seed check quick. Temporary garden fencing keeps a digger out of new bulb beds. A tick remover belongs in the first-aid kit before the first tick appears, and a flea comb helps you spot trouble early.

Wildlife Comes Closer

Fledglings, nests and burrows appear in gardens and on walking routes that pets think of as theirs. A dog that finds a grounded fledgling is usually just curious, but parent birds can be disturbed, so call your dog away and leash it near known nests.

Outdoor cats hunt on their own schedule. Keeping cats in, or in a catio, during peak fledgling weeks, especially early mornings, reduces encounters far more than hoping curiosity fades.

Frequently Asked Questions

Questions from the first warm weeks.

How can I tell if a grass seed has gone in?

Sudden limping, constant head-shaking or ear scratching, or repeated sneezing straight after a walk in long grass are the usual clues. Book a same-day vet visit rather than waiting.

Which spring bulbs should I fence off?

Daffodils, tulips and hyacinths are the commonest troublemakers. Fence new beds while they establish, and call your vet straight away if your dog eats a bulb.

Are lilies really that dangerous to cats?

Yes. True lilies and daylilies can cause serious kidney harm in cats, even from pollen or vase water. Keep them out of the house and call your vet at once if your cat may have been exposed.

Is a small taste of Easter chocolate worth calling about?

Yes. Don't try to judge the amount at home; phone your vet, who can work out the risk from your pet's size and the type of chocolate.

My dog found baby birds in the yard. What should I do?

Call your dog away calmly and keep it clear of the spot. Leash it near known nests for the next few weeks.

Do indoor-only pets need to worry?

Much less about seeds and wildlife, but fleas can still come in on other pets or people, chocolate is just as reachable indoors, and lilies in a vase are an indoor danger.

This is a seasonal awareness guide, not a substitute for an examination. A lodged seed, a chewed bulb, lily contact or swallowed chocolate all deserve a same-day call to your vet.
