I make a pledge to find my camera this weekend to get pictures of Toby and Tilly playing together.
However, a really fun thing that they do is trading. Toby will be chewing on his nylabone and while Tilly loves nylabones, she can't get it away from Toby. So she will just zip off to my roommate's room where all of her coveted squeaky toys are and grab one of them. She comes flying back into the living room and drops it a foot or two from Toby, takes a step away and waits. Naturally Toby sees a squeaky toy and goes "OHMIGOSHanalivetoy!" and drops the nylabone in favor of the squeaky. Tilly immediately swoops in, snatches the nylabone and scurries off underneath the coffee table where Toby doesn't fit to chew on it.
She has done this on multiple occasions and it really is quite funny to watch because Toby falls for it every time. ^_^
What do your dogs do that never ceases to entertain you?
