(I hope I posted the link correctly - I'm an old dog (*itch?) trying to learn new tricks!)
I think it's got some wonderful items that are pretty hard to find for people with little dogs - even simple things like leashes with clasps that aren't huge. Which seems like no big deal - until you try to find one. We've only got "superstores" around here, and they don't understand that a two-inch metal clasp is too bit for a 9-pound dog!
