If you’ve ever wondered where your dog is most likely to pick up a dangerous parasite at the dog park, researchers from Trinity College in Dublin have an answer: the entrance. This area, more than any other in the park, harbors the highest concentration of roundworm (Toxocara canis), a parasite that can lead to serious health problems for your dog if left untreated.
Roundworm, while often asymptomatic, can cause blindness and seizures. It’s particularly concerning because it’s easy for dogs to unknowingly ingest infected feces while sniffing around or during social interactions with other dogs. Around 11% of dogs worldwide are believed to be carrying roundworms, making the potential for exposure at busy, high-traffic areas like park entrances significant.
Researchers found that dog parks, regardless of their location or size, all shared one commonality: the entrances were consistently the areas most contaminated with roundworm. This makes sense because the entrance is where dogs are more likely to relieve themselves due to the strong scents left by previous park-goers. Additionally, entrances are unavoidable areas that all dogs must pass through, increasing the risk of exposure.
To minimize your dog’s risk of roundworm infection, regular deworming is essential. Monthly pills that target a variety of parasites are commonly available and can be mixed into your dog’s meals or treats. Above all, it’s important to pick up after your dog—properly disposing of waste can significantly reduce the spread of parasites like roundworm in public spaces.
While humans can also contract roundworm, our immune systems are better equipped to fight it off. However, being vigilant in maintaining cleanliness in shared dog spaces benefits not only our pets but everyone using the park.
