toy questions for "Dog People"

[critters]

These are the prototype dog toys my crafter came up with, and they're made out of jute. http://handicappedpet.net/helppets/v...hp?f=1&t=11713 Besides this green, and, of course, natural brown, the other colors of jute that I was planning to get for her (red, blue, pink, etc.) are $7 a roll HIGHER. This would add, like, $3 to the cost of a toy. I'm wondering if it's worth it to people or a "don't bother." Also, should we have bigger sizes of the "Moon Pies?" (We need a name for them. LOL) I thought maybe the 4 inch ones would suffice for little puppers and big ones too, but what do I know??

Thanks for your thoughts!!
