Spring Is Here -- and So Are the Hazards
After months of short, cold walks and cabin fever, spring feels like a celebration for both dogs and their owners. Longer days, warmer weather, and new smells everywhere. But spring also introduces a set of seasonal hazards that can catch dog owners off guard.
Here are eight spring dangers every dog owner should be aware of, along with practical steps to keep your dog safe.
1. Lawn Fertilizers and Pesticides
Spring is peak season for lawn treatments, and many common fertilizers, herbicides, and pesticides are toxic to dogs. Even "pet-safe" products can cause gastrointestinal upset if ingested in large quantities.
How to protect your dog:
- Keep your dog off freshly treated lawns for at least 48 hours, or as directed on the product label
- Watch for small granules on grass -- dogs can ingest them or absorb chemicals through their paw pads
- Wash your dog's paws after walks through neighborhoods where lawns are being treated
- If you treat your own lawn, store all chemicals in sealed, elevated locations your dog cannot reach
Signs of poisoning: Vomiting, diarrhea, drooling, lethargy, difficulty breathing, or seizures. Contact your veterinarian or the ASPCA Animal Poison Control Center (888-426-4435) immediately.
2. Toxic Spring Plants
Many popular spring flowers and plants are toxic to dogs. Some of the most common include:
- Tulips -- The bulbs are the most toxic part and can cause intense gastrointestinal irritation
- Daffodils -- All parts of the plant are toxic, with the bulb being the most dangerous
- Azaleas and Rhododendrons -- Even a few leaves can cause vomiting, diarrhea, and potentially cardiovascular collapse
- Lily of the Valley -- Can cause serious cardiac issues
- Sago Palm -- Extremely toxic; ingestion of any part can be fatal
How to protect your dog: Familiarize yourself with toxic plants in your yard and neighborhood. If you are planting a garden, choose dog-safe options like sunflowers, snapdragons, or marigolds. Supervise your dog outdoors and discourage plant chewing.
3. Ticks and Fleas
Ticks and fleas become active once temperatures consistently stay above 40 degrees Fahrenheit, which means spring is prime season. Ticks carry Lyme disease, ehrlichiosis, anaplasmosis, and Rocky Mountain spotted fever. Fleas cause discomfort, allergic reactions, and can transmit tapeworms.
How to protect your dog:
- Start or continue year-round flea and tick prevention (talk to your vet about the best product for your area)
- Check your dog for ticks after every walk, especially in wooded or grassy areas
- Pay close attention to the ears, armpits, groin, and between the toes -- ticks favor warm, hidden spots
- Keep your yard trimmed and leaf litter cleared to reduce tick habitat
4. Seasonal Allergies
Dogs get seasonal allergies just like humans, though their symptoms tend to show up on the skin rather than as sneezing and watery eyes.
Common allergy symptoms in dogs:
- Excessive scratching, licking, or chewing (especially paws, belly, and ears)
- Red, inflamed skin
- Recurrent ear infections
- Hot spots
- Watery eyes or runny nose
How to manage allergies:
- Wipe your dog down with a damp cloth after outdoor time to remove pollen
- Wash bedding weekly in hot water
- Bathe your dog with a gentle, oatmeal-based shampoo as needed
- Talk to your vet about antihistamines, prescription medications, or allergy testing if symptoms are severe
5. Standing Water and Puddles
Spring rain creates puddles and standing water that may look harmless but can harbor bacteria, parasites, and chemical runoff. Leptospirosis, a bacterial infection spread through contaminated water, is a particular concern in spring.
How to protect your dog:
- Discourage your dog from drinking from puddles, ponds, or standing water
- Carry fresh water and a collapsible bowl on walks
- Ask your vet about the leptospirosis vaccine, especially if you live in a high-risk area or your dog spends time near water sources
- Be especially cautious after heavy rains when agricultural or lawn chemical runoff is most likely
6. Open Windows and Balconies
As temperatures rise, we open windows and spend more time on balconies and decks. This creates fall risks for dogs, especially small breeds, puppies, and dogs who get excited by birds or squirrels.
How to protect your dog:
- Install secure, sturdy screens on all open windows
- Never leave a dog unsupervised on a balcony or elevated deck
- Make sure screen doors latch securely -- dogs can push through loose screens
- Be aware that even calm dogs can react unpredictably to wildlife they spot from a height
7. Bee and Wasp Stings
Spring brings pollinators back in force, and curious dogs often investigate buzzing insects with their noses and paws. Most bee stings cause localized pain and swelling, but some dogs have severe allergic reactions.
What to do if your dog is stung:
- If you can see the stinger, scrape it out with a credit card (do not squeeze it, as that can release more venom)
- Apply a cold compress to reduce swelling
- Monitor for signs of an allergic reaction: excessive swelling, difficulty breathing, vomiting, collapse, or hives spreading across the body
When to seek emergency care: If your dog shows any signs of anaphylaxis (facial swelling, difficulty breathing, collapse, widespread hives), get to a veterinary emergency clinic immediately. Ask your vet whether keeping diphenhydramine (Benadryl) on hand is appropriate for your dog and what the correct dosage would be.
8. Foxtails and Grass Awns
Foxtails are barbed seed heads from certain grasses that become a serious hazard as they dry out in late spring and early summer. They can embed in a dog's skin, ears, nose, eyes, and paws, and because of their barbed design, they only travel in one direction -- deeper into the body.
How to protect your dog:
- Learn to identify foxtail grasses in your area (they look like bushy, bristled seed heads on tall grass stalks)
- Avoid walking through tall, dry grass during foxtail season
- Inspect your dog thoroughly after hikes or off-leash time in grassy areas
- Pay special attention to the spaces between toes, inside ears, and around the eyes and nose
Signs of a foxtail problem: Sudden, violent sneezing (nasal foxtail), head shaking or pawing at the ear (ear foxtail), limping or licking a paw (paw foxtail), or a draining wound that does not heal. See your vet promptly -- foxtails do not come out on their own and can cause serious internal damage.
A Simple Spring Safety Checklist
- Restart or verify flea and tick prevention
- Check your yard for toxic plants
- Secure all window screens and balcony access
- Stock up on fresh water supplies for walks
- Schedule a spring wellness exam with your vet
- Learn to identify foxtails if they grow in your region
- Store all lawn chemicals out of reach
Spring is one of the best seasons to enjoy with your dog. A little awareness and preparation goes a long way toward keeping it safe and fun for both of you.
