Lovely puppy. Congrats on the new family member.

Husky_mom - you do get white factored border collies. My own traditionally marked dogs threw some very white factored pups themselves. They were purebred. Some of them had even more white than Becky and some borders are practically all white. White dominating isn't allowed in the show ring but I still think they look quite pretty.
In the past, white factored dogs would have been used to guard flocks because they blend in more but they can herd as well as any traditionally marked dog too.

Our Jess has always had big chunky feet too. Neither of her parents did. Her mother had little dainty feet and her dad had very little dainty hind feet but larger front ones. Jess has been clubby things on all fours, haha.
