Canine experts share 10 common garden hazards that could be putting your dog at risk this spring

The garden is a great place for dogs to explore, play, and relax, especially during the warmer months when they naturally spend more time outdoors. However, while many owners think of the garden as a safe space, it can actually contain a number of hidden hazards. Experts warn that features such as hot tubs, garden chemicals, toys, and even slippery decking can all pose risks to dogs if proper precautions aren’t taken.

To highlight some of these surprising risks, Platinum Spas Hot Tubs spoke to dog behaviour experts Karin Larsson-Bradshaw, trainer and animal behaviourist at The Dog Behaviourist and Dr Jacqueline Boyd, Senior Lecturer in Animal Science, Nottingham Trent University, and Canine Scientist.

1. Pesticides, weed killers and fertilisers

Karin said,

“One of the biggest garden hazards for dogs comes from weed killers, pesticides and fertilisers. Chemicals such as glyphosate can remain in the soil for years, and dogs are at higher risk of exposure because they walk barefoot, dig in soil, lick their paws, eat grass and sometimes drink from puddles. This can lead to vomiting and stomach upsets. 

“Even products marketed as ‘natural’ or plant-based are not automatically safe, as some plants are highly toxic in concentrated forms. Safety standards for pet exposure are often less strict than for humans, so owners should be cautious about any chemical used in the garden. 

“To reduce risk, avoid chemical weed killers where possible and use alternatives such as hand weeding, boiling water, weed burners, mulching or covering soil to block light. If fertilisers are used, keep dogs off treated areas for at least 48 hours and store pellet fertilisers securely so pets cannot eat them. Natural fertilisers such as manure, grass cuttings or nettle feed are generally safer options for pet-friendly gardens.”

2. Toxic plants to watch out for

Dr Jacqueline said,

“Many common garden plants can be surprisingly dangerous for dogs. Puppies in particular may dig up and chew bulbs like daffodils or crocuses, which are harmful when ingested. While fruits, berries, and shrubs can also pose risks if eaten in large amounts. Dogs can detect sweet tastes and enjoy them, even if it is masking something more unpleasant for their bodies overall. 

“Foxglove is highly toxic even in tiny quantities, and conkers or acorns can cause both poisoning and digestive blockages. Some plants, like giant hogweed, are hazardous on contact, causing skin reactions without ingestion. 

“Dog owners should regularly check their gardens, know which plants are risky, and contact a veterinary poison helpline immediately if their pet shows signs of exposure. A few minutes of caution can prevent serious harm.”

3. Decking, artificial grass and pebbles 

Karin said,

“Consider the surfaces your dog will run and play on, as some materials can pose unexpected risks. Wooden decking, for example, is often treated with chemicals to improve durability, so it’s essential to ensure any treatments used are pet-safe. Decking can also become very slippery, particularly when wet, increasing the risk of injuries to joints, backs, and ligaments, especially for older dogs.

“Artificial grass can also cause problems, particularly for dogs chasing balls, as it can create friction burns on paw pads and make it harder to grip and stop safely. 

“Patios and paving are generally safe, but they can become very hot in sunny weather, so dogs should always have access to shaded, cooler areas.

“Pebbles and stones are usually safe as a surface, but some dogs (that love retrieving) may start carrying or chewing them, which can wear down teeth or, in some cases, lead to swallowing stones and requiring surgical intervention.

4. Compost can be a concern 

Dr Jacqueline  said,

“Compost heaps can be a hidden danger for dogs in the garden. As garden waste breaks down, it can encourage the growth of fungi and bacteria, producing mould spores that may cause illness. Dogs are natural scavengers, and if they gain access, they may ingest food scraps or contaminated material, leading to digestive upset or more serious health issues. 

“Even compost applied to plants can be tempting, particularly if it contains added plant feed, minerals, or fertilisers. Keeping compost securely covered and out of reach is essential to protect pets while maintaining a healthy garden.”

5. Fencing should fit the dog

“A secure garden isn’t just about keeping dogs in, it’s about keeping them safe. Owners are legally obliged to keep their dogs under close control, and that starts with understanding your dog’s abilities and providing appropriate boundaries. Most dogs do well with 5–6ft fencing, though some may need taller barriers if they’re particularly agile or determined.

“Features like automatic-closing gates and interior locks add extra layers of security, while solid panels help prevent dogs from reacting to passersby or other distractions. Positioning boundaries away from public paths can further reduce unwanted interactions.

“Maintenance is key: fences weakened by storms or with gaps at the bottom can allow dogs to dig or squeeze through, creating obvious escape risks. Plus, there are some dogs, often described as ‘fence runners’, that enjoy running along the fences, meaning that any loose panels or nails could cause injury.”

6. Trampolines and play equipment

Karin said,

“Dogs jumping on and off trampolines could cause injuries if they bounce off them. They have no idea that the structure is bouncy, so it is important to show dogs that the trampoline isn't for them. Act calmly, giving them attention and stimulation when they do something or go somewhere they shouldn’t, teaches them it is fun. Instead, if safe to do so, ignore them or try to slowly walk them away from the toys or equipment using a long lead.”

7. Prolonged sun exposure

Dr Jacqueline said,

“Dogs can get sunburned, particularly in the garden during warmer months. Those with light-coloured fur, thin coats, or pink skin are most at risk, especially on exposed areas like the nose, ears, and belly. Even on cloudy days, UV exposure can cause redness, irritation, and discomfort, and repeated sunburn can increase the risk of skin damage over time.

“To reduce the risk, dogs should always have access to shade and avoid prolonged time in direct sunlight, particularly during the hottest parts of the day. Pet-safe sunscreen can help protect vulnerable areas, and owners should regularly check for signs of redness or sensitivity after time outdoors.”

8. Grass seeds 

“Grass seeds can be a surprisingly serious hazard for dogs, even in your own garden. They can easily become lodged in a dog’s fur, between their toes, or in their ears and eyes, and because they are shaped like tiny darts, they can actually penetrate the skin and travel through the body. This can lead to painful infections and abscesses, and in more serious cases, grass seeds can be inhaled and enter the lungs, sometimes requiring surgery to remove them. 

“Although it’s more commonly associated with dogs running through long grass in fields, it’s still something owners should be mindful of in their own lawns, particularly during the summer months.”

9. Hot tubs aren’t suitable for dogs

Karin said,

“Hot tubs are not considered safe for dogs due to a range of health and safety risks, with the two main risks being their temperature and the chemicals used. 

“The high water temperature, typically comfortable for humans, can quickly cause dogs to overheat because they cannot regulate their body temperature efficiently and rely mainly on panting to cool down. This can lead to heatstroke, organ damage, and, in severe cases, can be fatal. 

“Chemicals such as chlorine and bromine can also irritate a dog’s skin, eyes, and ears, and dogs may be tempted to drink the water, which can make them unwell.“

10. Bird feed

Dr Jacqueline said,

“Bird feed can also pose an unexpected risk to dogs, particularly fat balls and suet products, which are very high in fat. If eaten, these can trigger pancreatitis, a painful and potentially serious condition that can develop either gradually or very suddenly. Dogs are often attracted to fallen bird food or feeders they can reach, so it’s important to keep feeders out of reach and clear away any food that drops onto the ground.”

Ultimately, keeping dogs safe in the garden comes down to owner awareness and responsibility. Avoid leaving items around that dogs could chew, swallow, slip on, or injure themselves on, and regularly check your outdoor space to make sure it’s as safe as you think it is. 

Just as importantly, dogs shouldn’t be left alone in the garden for long periods or on a regular basis - they need exercise, stimulation, time in nature, and opportunities to socialise, as well as to feel included in everyday family life. Alongside managing physical hazards, proper and consistent training is key to keeping dogs safe, healthy, and happy.
