Not Durable Enough
Color: Colorful, Color: Colorful
These worked SO WELL... For one night. Maybe my pupper is just super destructive with his chewing, but he had a chunk of the top of the pineapple off less than 10 minutes after opening the package. That being said, the concept is perfect. He is very active when I'm trying to settle him down for the night if he hasn't had enough activity during the day. This translated to him trying to chew everything (including my arm, and RIP my comforter...) I wanted to find something for him to chew on that would help sooth his teeth/gums, since the other toys he loves weren't interesting enough to keep him engaged. Unfortunately, despite one night of his chewing relaxation, he chewed right through them. At least I know the concept of a frozen chew toy is the correct intervention. I'm just sad that these were destroyed so quickly!

Lay flat handle is a game change
This dog steak is made of quality steel easy to install and has held up overtime. I would highly recommend. I bought this dog steak over two years ago. Immediately and easily screwed it into the ground for a secure hold. The lay flat handle is convenient for attaching a cable or rope to tie your dog up to. The lay flat handle, makes it easy and convenient for mowing your lawn. I have never once pulled it or moved it in order to mow our grass and after two years, it has remained as secure as it was the day I screwed into the ground.
