Dog didn't really like them...
I have a basset hound. He will eat anything that is strongly scented, not strongly scented, might be food, or isn't food. These have a strong scent and arrived in surprisingly good condition. He sniffed one, sucked on it for a while experimentally, then spat it out and wandered off. He just wasn't really into them.
The texture is quite dry, almost sharp, which I suspect might be the problem. As for the cat, she poked one, batted it around the floor, then sent it skidding under the bookshelf.
