Spent the night with the nieces last week.
My 4 y/o niece enjoyed some dog powered sledding fun.
I towed her up the huge snowdrift out by their barn then Kenzi pulled her down
There was a really nice 100 ft gentle downward slope that had been shaped by two separate major snowstorms and the 10 or so ft of snow that we've gotten this season. It worked great and they both had fun!
Kenzi is a puller, but I think she would have been just as happy riding. Yup, we tried the dog riding in the tube earlier this winter and yup, my crazy snow dog loved that, too!
