    DefaultStudy: Labradors Gain Weight Due To Gene Deletion

    Almost 60 percent of Labradors in the US are overweight. And a scientific discovery says that it may be linked to a breed-specific gene mutation.

    Some dogs have a tendency to become overweight, despite keeping a controlled diet, limiting the amount of treats given, and going out for plenty of exercise. Canine obesity ranges between 34-59 percent in developed countries, and being overweight can cause significant harm to your dog (not unlike humans). And do you know how you blame your weight on genetics? Well, for Labrador Retrievers, a gene may actually be a cause of canine obesity.
    Did you know that Labradors have the highest risk of becoming obese as they grow older? Thanks to a recent study, we now know the reason why that might be.
    The study, which was published in Cell Metabolism, involved recruiting 310 Labradors that were both and service animals. Body shapes ran the gamut, from lean to “big boned and fluffy.” Scientists studied a variety of different genes and concluded that there was one gene, POMC, that was distributed differently between the lean and obese groups. POMC is a protein that helps control hunger, and Labs (along with flat-coat retrievers) are the only breed that were missing gene.
    They found that nearly 23 percent of Labradors are missing part of this POMC gene, a gene which helps dogs and humans feel full. Without this full POMC gene, some dogs aren’t aware that their body is no longer hungry and consequently, they should stop eating (I seriously feel this is the case when it comes to eating chocolate on my part, but until science proves that, I’ll keep that tidbit on the down low).
    Dogs with this kind of mutation are 2 kilograms (4.4 pounds) heavier on average and are 10 percent more likely to beg for food or hunt for scraps. With approximately 60 percent of U.S. Labradors considered obese, this may help those dogs who have the mutation control their weight.
    However, there is a bright side to all of this. Because Labradors have this gene mutation, they are also the easiest to train because they are motivated by food. Rewarding good behavior with treats or a piece of kibble is a surefire way to get your Labrador on its way to becoming a master of basic commands, complex tricks and even help someone you love who needs assistance in their day-to-day lives. Just make sure it’s low cal… there’s no reason why positive reinforcement has to go right to your Labrador’s hips!

    No. Labs are sometimes Flabradors because they eat everything under the sun and are professional beggars for people food which too many of us succumb to. By the way. That's too much food for one meal in the opening pic. They should get 1.5 cup of food twice a day.
    Feed em a big bowl of food like that and they will get fat!

    Ruby's filling out quite nicely as is her master too.

    "Rewarding good behavior with treats or a piece of kibble "
    If I rewarded Rocky with a piece of kibble he'd probably leave home, that stuff is just a base for the m-e-a-t.
