My high energy 43 lbs standard poodle mix loves this! He figured out quickly how it works and now eats his meals from it. The weight seems good, but he can pick it up and carry it to another room. We've had it two weeks and already there are holes in the surface and areas that his teeth have damaged the plastic so I don't know how long it will last - this does concern me considering the cost. It's attractive and it works.
