Anyone have suggestions on how to keep a dog busy while you're away? My mutt tends to get into trouble when he gets bored. I usually give him a kong stuffed with some peanut butter and treats but I'm looking for some suggestions for other long lasting treats or toys. Rawhides are out - he's plenty gassy already. I might look into bully sticks but I don't know much about them. Are they ok to give while the dog is unsupervised? Will they stain the carpet? What exactly are they made of?
