This is the harness I have for my 2, 9 mos olds....Harley was 12 weeks old and 2.2lbs when I got him, very thin...and this was the only harness I could find that fit him...XS and they are adjustable....he is still in it...I got the black for him and I've only had Ivy 5 weeks she is 5.4 lbs and it fits her and I still have some room to go...I got the pink one for her.
I got them at Pet Smart. |
