We began giving Saphyre a Kong filled with food because she has to spend so much time quietly occupied in her crate. She is very intelligent and grows bored easily -- and then begins licking her paws repeatedly. So the Kong seemed like a great fit for her.
She was very quick to empty it of dry food, and didn't like peanut butter. But she found a light coating of split pea soup absolutely enchanting -- and it made things sticky enough to keep it a puzzle for awhile. She now LOVES the Kong!
We do have to keep the Kong confined to the crate, though. She gets way too active with it in an open room -- too active for a dog on heart worm treatment. She'll be great fun for a family once she can be be active. And we figure keeping the Kong as a crate only treat will help her time spent quiet pass a little better.
