Not a day goes by that my dogs don't give me a good laugh. Usually it's either Mags or Jack, and sometimes both together. This morning there was a mad chase around the place for a few minutes followed by a tug-of-war after Jack found one of their favorite toys in the grass. This struggle went on for a good five minutes with neither competitor giving an inch. Jack is strong enough that he can lift her off the ground and whirl her around. (She likes that apparently.) He's also strong enough to get it away from her with a couple of vicious, neck-wrenching snaps. But he doesn't. It's surprising how careful he is and how much he veils his strength advantage.
It's great fun to watch them enjoying each other.
