My Chubby Boy
I adopted an 8 year old dog August '23. He was in rough shape. Of course he's a spoiled little guy now and he's put on some weight. I had the small belly bands and they fit him great....except not around the waist any longer. As we work on weight control (for both of us) I am using the belly band extenders so I don't have to purchase more belly bands that will end up being too big for him. They work fantastic for what we need and hope they are only needed temporarily. Wish us luck!! Great product, highly recommend them.

These extenders are great
The extenders are great for making sure the belly bands fit my dog comfortably. I'm so glad they finally started making them for use with the XL belly bands, since the smaller size extenders did not align properly with the velcro on the XL bands.
