Hi, Scootergirl!
I'm glad you brought this up. I have, indeed, seen these and I've read the ingredient labels. I was very curious, but I can tell you that after looking at them in the pet supply store, I am NOT a fan, personally.
It's sort of the equivalent of feeding a sugary energy or "meal replacement" bar to a human instead of dinner...you CAN do it every once in awhile, but it's not really a great idea to do this routinely.
The ingredients utilize a lot of garbage fillers that I don't feed my dogs. The more processed food is, the less convertible nutrition you can actually extract from it, and this is very processed and "molded" to get it into the shape and consistency you see.
Also, I just noticed on the website it's a subsidiary of Mars, Inc., which tests on animals despite heavy public pressure to stop and instead use more modern and ethical testing protocols. To me, testing on animals while simultaneously trying to present yourself as producing animal-focused products is hypocritical, so I choose to put my dollars towards products made by companies who really stand for animal health and welfare on all fronts...not just in the "final product" stage.
To each her own, but it's not for my dogs. It could be a fun treat to keep a dog busy or occupied, or maybe even once in awhile for a travel meal, but that's about it in my book.
I hope this helps you!
Love,
Jen and Balthazar
