Gear: litter, leads and the rest
The things you buy again and again, and the ones you only want to buy once. See this line on the bill

Dog harnesses and leads, priced
Size guides on these five pages range from chest and weight to weight alone. I'd buy on the fit figures first, because a harness you have to send back saves nothing.
