Sydney uses a size 3 BB. She's on the second to the smallest hole. My mom and dad's Yorkie has the same BB size and uses the same hole. My mom had it looser and had Ginger running around the house to try it out. Sure enough, she got it caught on something and wiggled out.
I know what you mean about under the armpits. It does bow a bit, but it does the trick. Sydney is just over 5 lbs and she started on the smallest hole when I first got it. Because it's leather, there is some give. Perhaps it did stretch, but if she can wear it without wiggling out then you're safe. And $28 for a used BB and leash is a good deal. I would have bought it, too. I paid a little over $40 with shipping for Sydney's. There is another kind of harness that's made of material, but she slides right out of that one.
I hope this helps. |
