Welcome to Yorkie Talk.
What breed of dog do you have now?
I am a retailer of Buddy Belts because they are harnesses I feel good about selling. A member here introduced me to the harness and my boys have used them for 4 and 5 years now.
Durability is just one of the things I love about them. Here are Max and Teddy's primary BBs, the Classic Black, photo taken just now (dreary day here, so a little dark):

The boys wear these daily and have put plenty of mileage on them. These harnesses are 3 and 4 years old.
The solid color, smooth leathers are the most durable. Metallics, some snakeskin textures, and suede editions are more likely to show wear after awhile, but still very long lasting compared to other harness materials. The interior leather, the part that touches the dog's body, darkens with age like the interior of a leather shoe.
I have seen 9 year old Buddy Belt harnesses on the BB Facebook page that look amazing.
