Here's Ella's Kong Sundae (I've posted it before, but I'll post it again):
Wonderful Houndlove got me into giving Ella her meals out of kongs. I read a thread or something by her on another board and I thought, "BRILLIANT".
Ella doesn't always get a kong sundae.
But the kongs in that picture are filled with kibble, plain yogurt, and raw beef heart.
The blue one is a King Kong and the red is a 3 1/2" kong that fits nicely into the blue one. I seal around the outside of the two with peanut butter and then I freeze it.
YUM. She goes mad over it.
