My dog sniffs car leaks. Are spilled car fluids dangerous for dogs?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed | Male | unneutered | 20 lbs

hello, this might sound like a weird question but sometimes my dog sniffs that circled part of a car because there’s something there (probably pee, since he then also wants to pee there), but i’m always afraid that it’ll be something else dangerous. i don’t understand a lot about cars but if something dangerous was spilling from it, it would likely come from underneath and not the front right?

Thanks for using Petco Pet Education Center, formerly Petcoach! Sniffing around the car is not concerning. And you are right, fluids leaking from a car could be dangerous (antifreeze and oil); however these fluids need to be ingested to cause a problem. I hope this helps! Good luck and kisses to Alex!
