So my Jack Russel, Chase, is one of those dogs inbetween sizes. If i get a large, I have to redo it smaller, and vis versa with mediums. And since we take him to the park a lot, and do a lot of hiking, I figured he could use a back pack, and after gawking at the $20-$50 price tags, I decided it would be waaayyy easier, and a heck lot cheaper to just make him a back pack. Did I not mention I don't owna sewing machine? Or that I have corpal tunnel in both wrists? This easy project turned into a month-long event. But I did it! and for under $5! ( I had a few old leashes, bc my other dog went through this "I will eat you, leash" phase...) And, I don't measure, I flop the material over whatever I'm making it for and wing it. Did I mention Chase doesn't know he's a JRT? He's very mellow, doesn't even bark!

Ignore the mess on my dinning room table, the epiphany hit me during my morning coffee...
Anyways, thats the foundation of the backpack: a big oval. You need to cut 2, and sew them together.

These are the pockets.

sew the pockets on, add adorable little buttons that really have no purpose, except to hide the mess I made sewing in the snaps...

Add straps, and Tah-Dah!
