"I purchased a Knotty Dog for Lola, our 18 month lab/shepherd mix, and she loves it. She hasn't chewed through it yet, but as you can see, she is doing her best to get to the middle."

“Thank you so much for the "Knotty Dogs". Our kids loved them.
Kismet was on a mission the minute she got it.”

“I bought two...and came home and gave one to Tucker to see what he'd do with it. Two hours later, he finally pooped out, and is only about 1/2 of the way into the center--although I think he's gotten a few treats out to keep him motivated. Mind you, this is the dog that can destroy any other toy or food-dispensing apparatus in seconds flat... Unintentionally, I took several pictures of him chewing the knot with his Kong ignored at his side.”
