Did you end up finding the collars you were looking for? i just ordered 2 from
Soft Martingale Collars
I ordered just some plain ones with nothing extra on and then ended up ordering matching 3 ft leashes with snaps on both ends to attatch to my belt. The woman is very nice and prices were awsome leashes and belts look very soft and flexible so am sure she could help you.
I should receive next week or you can check out my plain ones on my facebook page.
Have yourself a great day and waiting for updated pics on that baby boy of yours
