Thanks all! Ok, here’s the deal: the group has already purchased some doggie-bone-shaped cutters, which are simply a flat 5/8" strip, shaped like a bone, and spotwelded. A couple are thin stainless (cheap),
and a couple are thicker, of copper (more expensive, but they seem to be much higher quality). 
The cutters are difficult to use for volume production, since they lack a good wooden handle
atop them for exerting pressure and rapid stamping. E.g., 
Time is money. They tend to cut into your hand slightly too.
Also, the thick dog biscuits tend to not bake to done in the center, unless they have 3-4 holes punched down the center too.
So I’d add three nails thru the handle down thru the cookie for this. Cheap.
SO> we really need to either make some custom cutters from scratch, or modify the ones we have.
IF we can find someone to help us make them from scratch, use stainless, shape them into dogbones (in two different sizes), attach an handle and nails coming down from the handle to make the center holes, then we’re doing well. If we can get this done so one stamping motion produces 2, 3, 4, etc. cookies, even better.
We are doing this for charity and have a low budget, so if anyone can help with this, that would be awesome. Especially if anyone is good with bending, crimping, spotwelding, etc.
Is there any way we could impose on someone to help us get these made, perhaps as your contribution to helping the animals? If not, that’s okay, the advice is still appreciated. I’ll follow up on it more later this week.
Cheers!
