Little kids like mud. Dogs like mud. Why not bring them all together for a fun, messy good time? Of course kids and dogs like getting all dirty. They never have to clean everything. If I didn't have to do my own laundry I'd jump in the mud all the time. As it is now I need to try my best not to sweat just so I don't have to clean the shirt for one more day. That's the level of broke we're dealing with. Kids and dogs don't have to worry about that at all. Jokes on them. By the time this little girl and dog grow up, there won't be anymore water on Earth for them to clean themselves. Suckers!
I think that might be a lab, and if there's one thing labs love, it's to get messy. If you own one, expect it to smell unless you wash it constantly.
