When I’m out walking dogs I often see a lot of dog fur that’s being left out for birds which I thought was an amazing idea until I started seeing these types of articles.
🐶 You should not leave dog fur out for birds because flea and tick treatments on the fur can contain harmful chemicals that poison birds, eggs, and chicks. Recent research shows that these chemicals increase chick mortality and reduce egg production in birds that use contaminated nests. Instead of pet fur, provide safe, natural nesting materials like untreated wool, moss, twigs, leaves, and grass clippings.
🐶 Why pet fur is dangerous
⚠️ Chemical contamination ⚠️
Veterinary flea and tick drugs are designed to stay on the fur, and birds can ingest them, leading to increased toxicity.
🐣 Harm to chicks:
A study found that the more pesticides present in fur used in nests, the higher the chick mortality.
🌲 Environmental impact:
These pesticides can also harm other insects and the wildlife that depends on them.
🐤 Safe alternatives for nesting materials
Instead of pet fur, provide natural and safe alternatives for bird nests:
🍁 Natural fibers:
Offer untreated wool or plant-fluff like cottonwood, which is a soft, fluffy material birds are attracted to.
🍁 Plant materials:
Leave out natural materials like dry grass clippings, twigs, leaves, moss, and straw.
💦 Water and mud:
Provide mud in a small area for birds like swallows, swifts, and robins that use it for their nests.
🪺 Install a nest box:
Support birds by providing a proper nest box.

Attention Pet Owners & Bird Lovers!
Please do not put out treated pet fur for birds to use in nests.
Our latest research with University of Sussex revealed that pet fur treated with flea medication contains harmful chemicals that end up in birds' nests. This has been linked to higher mortality rates in chicks. The very thing we do to care for our pets could be inadvertently hurting our wildlife.
As pet owners, we deserve to feel confident that we're keeping our pets healthy without devastating the ecosystem. That’s why we’re calling on the government to take action and carry out a comprehensive environmental risk assessment of veterinary drugs.
But there’s something we can all do TODAY: Have a chat with your vet about the best flea treatments for your pet and how often they should be used — for the wellbeing of both your pet and our planet.
