Thanks for this topic!

We are huge
Cesar Millan fans (

) and when we adopted Maya, one of the first things we purchased along with a leash, collar, crate, etc was a doggie packback. We trained her with it from day one because Millan said this was a simple way to give a dog a job (mental exercise) as well as increase the physical exercise.. She now carries a bottle of water (20 oz) on each side of the backpack along with extra poopie bags.
We did not however, do good research on doggie backpacks and ended up with one that doesn't fit her well. Since it's more important to us to get her into weight pulling for example, we're putting off purchasing a better one for later. Does anyone have any tips for backpacks that rub at all?
Here's a pic of Maya in her backpack getting a huge drink of water from the cooler.
