While it is possible to spend endless amounts of money on dog toys, it is just as easy to entertain Emmy with things we already have. Here she is content to pull against Charlie on a length of rope. It keeps them both amused and cost nothing.
I gifted her with a paper grocery bag which I opened and dropped near her. She has spent a lot of time making sure that the paper bag knows that it has met a fierce opponent. When she gets bored with it, I simply rearrange it and drop it again. For her it is a brand new adversary.
Sure she has the attention span of a rutabaga, but she is hilarious!
