5 1/2 year old Rhodesian Ridgeback/Boxer mix.
I call him my California hippie dog because he only likes the hippie-esque type snacks. He's also exceptionally picky.
His average, every day snack is usually a Blue Buffalo Health Bar. I don't love BB as a whole but he absolutely loves these so I buy a bag when I order dog food.
For a more intense chew session, he gets a 12" braided bully stick. That doesn't always last very long but he loves it so I give him one every few weeks. Other times, he chews on it for a few minutes, buries it, then comes back to it later.
I tried Zukes Z Bones as a dental thing and he ate one so I thought he liked them! I ordered 2 bags! Now all he does is hide them. So that was a waste. Every so often he gets a bug up his butt and decides he wants to eat one and digs it out and chows down. He does like the Zuke's fillets at least.
And for training, I have to use hot dog or cheese. He isn't motivated by anything else.
