Lol, Trey looks like a giant moving furball when he runs.
Summer though, is graceful. She is just way more efficient and exact in her movements than the rest. I love watching her run because she just loves it so much. Nard loves it too, but he usually looks like a dweeb running or that he's been smashed into the ground.
I bet Summer's coat has doubled in length since getting her and getting her spayed. I'm hoping though, that it's about done! It's pretty now, but so much less upkeep than the rest. It'd be nice if it stays that way.
