Do some google searches for dog boutiques and pet/dog purses. Most boutiques carry the same styles & brands so you'll get an idea of what's most popular, the best quality & reasonably priced. Amazon does have a really wide variety, but the quality is hard to tell without having first-hand knowledge of the brand you're looking at. There are a lot of "fakes" on there, too, but if you know what you're specifically looking for, Amazon can be a great option!

I got a small Jaraden Getaway bag from YT member, LIL SIS & am thrilled with it. I also really liked the looks of Kwigy Bo bags, but they're really hard to get ahold of, so if you aren't physically seeing one in a store, you could be out of luck for a while. Those are a bit pricier brands, but they had what I was looking for and are a good start to see what else is out there.
