Interesting article about a genetic mutation that is linked to obesity in humans and Labs! One researcher found about 20% of labs have the mutation that makes them more prone to obesity and that about 75% of a set of seeing eye dog labs had that mutation, maybe making them easier to train. How many of you think your dog would persist in trying to get the hot dog out of the hamster cage?
