Wow, those treats look good enough to eat!! Thanks for sharing the link.
Here's one of my favorite sources for quality dog cookies:
http://www.dogcookiebaker.com/
The owner is a very reputable mastiff breeder who also runs a dog cookie store with no nasty ingredients. They also have other treats like bully sticks and moo tubes, etc, and her prices are unbeatable. My pup's absolute favorite is the lion-shaped Beefy Vegetable cookie. When you open the bag, you can SMELL the beef! Mmmmm. No wonder my pup goes bonkers for them.
