I took my dog to the park in the snow. She is very small and while running around in the snow, hard, icy "snowballs" formed on the fur on her chest. How and why did this happen?Alix Buttimore, (aged 11), London, UK
this is perhaps the greatest mystery science has to solve. once science can explain why snowballs formed on your pet dog we will be able to explain everything. we need to study this in greater detail and learn to understand how this can happen. maybe you have an idea or theory about this?
There's no reason to be snarky, Douglas, and plenty of reasons not to be.As for your question, Alix, the answer lies in the texture of your dog's coat, which I suspect is rather like human hair. You might find it instructive to compare a few strands from your dog's coat with the fur of a snow-going breed, especially under your school's microscope.
When I had a moustache this would happen to me too. Maybe it was formed by both snow sticking to the hair and vapor (from my breathing, and in your case from the dog's panting). I've seen this form on dogs' feet (the hair between the pads on their feet) however. I understand their feet are hot, i.e , they lose body heat through their feet and maybe the body moisture vaporizes there. It's probably a combination of moving snow over hairs and possibly water vapour from the body. Just my theory.
perhaps the snow forms on the hairs sticking out as she runs, because they brush against the snow. Then the small balls of snow act a surface for the snow to cling to, tehrefore:Small snowballs = bigger snowballs!
