I've also ordered off zozotees.com and it's great for Canadians as American shipping/duties/taxes are always so expensive. Their shirts are cut especially so dogs can still do their business. The shirts are reasonably priced and pretty cute.
There's also a website doxidelight.com -- you can get a custom sweater for your dog. A little more pricey, but may be worth it. Not sure of quality, never ordered from them
Happy shopping!
