My 2 year-old terrier mix really loves to play tug and tear open her stuffed toys (we’ve gone through 3 of these Lamb Chops in the past month, her absolute favorite), what a mess ? . But I wanted to get something for her to do when we aren’t around so she can do something to stimulate her mind and instinct. She loves to track. Does anyone recommend a type of toy we could use? She loves the classic Kong, but that only lasts a little bit, and I don’t want to stuff something with too much food. Maybe something where she can open different compartments to find a single kibble here and there?
