Kongs are awesome toys; safe to leave with your dog, easy on teeth, keeps them busy and takes awhile to clean out completely. Katie did not like the stuffed kong in the beginning. She would lick it a couple times and be done. I had to hold it and encourage her. Here is a video from a few weeks ago:
After a couple weeks with the kong, Katie is a champ at cleaning it out. She is so smart; holding it, rolling it around and batting it with her tiny paws: total Kong-Quest.
Now that she has become a pro, I make it super difficult and it takes a good 30-40 mins for her to get all the goodies out.
Is she not the cutest thing in the videos? *swoon*
