I don't have dogs to provide taste testing critiques so I'm counting on you Chowhounds for suggestions!
I have a large number of healthy active dogs that I see frequently. I'd like to give homemade shelf stable treats as a holiday gift this year. Points if it can be cut out with a cookie cutter and made a week or more ahead of time. It would be fun to make several varieties, especially if the colors varied.
Thanks in advance - looking forward to the ideas!
