Well I actually broke down a bought the size 3 to see if it fits a little better than the 3.5.. should be here this week

So we'll see

If not its easily returnable. Maybe its just her build but for me the size 4 was WAY to big and the size 3.5 fits nicer but still fits on the second to last hole for a snug fit so I'm hoping the 3 can fit on the 3rd or 4th hole and be snug
I acually made my own liners for the BB but I only wear them when she is in a short coat. When her coat is longer I don't wear them because it seems to mat MORE for her.
Also wanted to add that the first one I got she wore to the beach all the time and we had no major issues. I actually gave that one to my mom and got Mitzy a new one

I'm a harness addict too and feel like I've been through EVERY harness, Cindy's, the Choke-free, Puppia, the suede step ins, just plain nylon harnesses, but NOTHING compares to the Buddy Belts

I just love it!! Especially because we walk everyday so its nice to have something so reliable and that I love. I still use the Puppia Vest in her carseat and I kept Cindy's that I use on occasions, but that's it. I gave the rest of the harnesses either to peope I knew with small dogs or to the shelters
