Sometimes I make her wear a backpack, but it's just some generic thing I got at a garage sale for $5. It's a little big for her, so I never make her wear it on long hikes, and I usually just put a small bottle of water and her collapsable bowl in it. I honestly don't like it very much and don't use it too often.
What I really like to have her wear is one of these harnesses (except it's purple and not Lupine):

I can grab onto the little piece on the back pretty easily, which is nice if I need to snag her for some odd reason. Also if we are scrambling up boulders or on rough terrain, I would be able to grab onto it to help her out, although she has never needed it.
(I just realized that both of those are second-hand items. One from a garage sale and the other from the dog rescue's resale store
)
I would really love to get a Ruffwear Webmaster and/or one of their backpacks. But that's a lot of $$. I'll probably end up finding a secondhand one. I'm sure Fable won't mind.
