Anyways, I haven't posted here forever. I was just wondering, my dog is getting pretty old, and recently she's been having troubles. I got three sets of stairs that I run down than back up when I bring her for walks and normally she runs up them no problem... but lately every once a week or so she kinda stumbles up them like her paws or ankles are hurting, but the wierd thing is that it never lasts. One day she'll be limping that always within a day, and usually with in an hour or so, she gets better. Are there options out there to help keep my dogs joints healthy? By the way she's probably nearing 11 or 12 and is a Dalmation / Border Collie.
