Construction sites pose an exceptionally high risk of sharp object injuries for dogs. Power tools, construction materials, and debris can all pose hazards to dogs who wander onto construction sites. Additionally, loud noises and unfamiliar surroundings can cause stress and anxiety for dogs, increasing the likelihood of accidents. Pet owners should keep their dogs from construction sites and ensure they are securely confined or supervised near potentially hazardous areas.

Preventing injuries from sharp objects requires proactive measures on the part of pet owners.
