I hope she gets to go to doggie camp, too! Ours love it as well - lots of fresh air (relatively, since it's up in the hills) and exercise, although this last time, given their ages, they spent time in the "geriatric" section.
But I think one of them may be older than we thought - we adopted her from a shelter, so it was anyone's guess how old she was back then. Right before we left on vacation she had problems using her back legs, but we finally determined it was just one of them and that she probably injured it somehow. I freaked out, though, when I went online to look up possible causes and one was this degenerative disease that has no cure and eventually they die from it! So we were quite relieved when she was more noticeably favoring one leg over the other and got back to almost normal before taking her to camp.
Lately, though I've noticed she's probably losing her hearing now, as she just looks at us with a slightly dazed expression when we're talking to her.
