I didn't take the kids to work today because it was pouring rain outside and it's hard to juggle two Yorkies an umbrella and a big bag. I got home and Pepper greets me at the door, but Brownie's nowhere to be found. I call to her and she slowly appears, limping. I check her all over and she doesn't seem to be hurt and no broken bones.

I make her walk back and forth for a while and then she seems to slowly put pressure on her leg and now she's walking fine. Is this a sign of arthritis? She's only 5 years old, what could it be?
