Jedsmom - I do make silk collars with break-a-way buckles and I do have bells and would be glad to help you. To be honest, though, the break-a-ways only give a false sense of safety. The buckles that I have take a considerable amount of pressure to release. Bells hang down and can get stuck in numerous ways that we would never think of - floor vents, a loose string in the carpet, etc. and I honestly don't think a tiny could exert enough pressure to make the collar release without causing damage.
The safest option for a bell is the "D" ring on a harness. |
