I tried to draw my dogs in snow, but because I'm not good at art and I don't know dog anatomy, they look a bit strange. (also my dogs move to much for me to get reference images)
Thanks to my dogs for existing (these are my real dogs I have) The black one is Whiskey (yes, that's his name). He is a pure-bred Labrador Retriever. I drew him rolling around because he loves that. The black, white, and orange one is Boots the Corgi, named after the fact that she looks as if she is wearing boots. I was planning to draw her with her tough out, but it looked very bad when I tried, so I scrapped the idea. The white and brown one is Dottie, she is a mix of a Pitbull and a Boxer. She doesn't like the snow, so she is cold and unhappy.
