The first one of these I purchased was great. My heavy chewer and light chewer both enjoyed it with supervision for well over a month. I bought 2 large ones the second time. I read poor reviews of other brands so I went back to what we had liked. (Kong) This time the heavy chewer finished one in a couple hours. The light chewer didn't make too much of a dent in his but the marrow came out a dark thick brown and left horrible markings - it looked like a puddle of thick dried blood. The stain will never be completely gone. I'm frustrated that I spent so much money for what turned out as a couple hours of use and a mess that makes me want to throw away the other. I wish I had taken a picture of the stain- I was just too horrified and wanted to try and get it out!

Keeps my Doberman occupied for hours. she loves carrying it around the yard and house. easy for her to handle.

My GSDs love antlers but it is hard to find good ones. One that are priced good too.

I have one "power chewer" and one who doesn't like to chew so she gets tartar build up & needs dental cleanings often. The power chewer is satisfied, and Miss Tartar has successfully cleaned her own teeth!
