I have a GSD who despite being a working dog, as soon as she had any time alone or just to “chill” would chew on absolutely everything, I ordered this on a whim from adverts on Facebook and I am so glad I did.
It took her a couple of hours to go near the camel skin, she’s wary of anything new so I gave her time to figure it out but once she understood the concept it has remained within close range of her at all times and seems to be working to satisfy her chewing urges!
