Right now you have to pet the dog extremely often because the bond goes down so fast. I would propose to scale the time for the dog to lose one bond level by factor 8 to 10.
Why? Because this minigame certainly becomes a sort of micromanagement if you have to feed your dog 10 or more treats on hunting session. It would become a really fat dog, if this was real.
Please make this minigame less often necessary. Just lower the speed of the dog losing bond by a large factor. Thanks.
