PABS Dog Chastity - Chastity for Dogs - Pet Anti-Breeding System (Storage Travel Bag - Dog Period Pads Option Available (Dog Chastity & Storage Bag - No Sani-T Pads, X-Large (55-90lbs))

This works well as long as the dog doesn't chew through the straps. We sprayed the entire contraption with bitter apple before putting it on. We praised our dog and made her feel like she was special for wearing it(she can easily tear it off if she wanted). She's a livestock guardian so she runs all day and has a very active life. It'd be great to have much stronger material for large working breeds. The back strap tore in half after 5 days. Glad there are replacement parts.

this thing was extremely difficult to put on. It fell off very easily. it is ugly. the return period is very short.

Very happy with this product.
