I bought Max a $5.00 children's back pack on sale at Walmart last week and it's his favorite thing ... he's only 5 1/2 lbs.
It's the kind of pack that's popular right now ... over one shoulder. It has a cell phone holder, good for treats/cookies and a front lower zipper good for leash and poop baggies, etc.
I put Max's favorite little blanket in it and he rides around in the main section with the zipper only closed enough to keep him feeling snuggled, up against my chest.
I've had so many people ask where I got such a cool/comfortable 'dog bag' ....
It's almost embarassing to say Walmart, $5.00 bucks!, lol!
