Wow, what a difference this has made for our Australian Shepherd mix, Harley. We rescued him 2 years go and he's always been very skittish, even with our own family, especially if we're carrying something in our hands. We think he may have been abused before 😔. Also, he was never really good with strangers, and we could't really walk him freely in our neighborhood. After a couple of days giving him Tessera Naturals treats twice a day, he's been sooo much better. He's way friendlier with visitors and seems much more mellow all around. He's a real joy now, thank you Tessera Naturals!
