This has been discussed on here before but one thing I don't understand is why Labradors in particular have this apparent compulsion to eat. All dogs, whatever their breed, size, age and so on have to eat to survive but Labradors take this to the next level. I'm not sure they are a unique breed in this respect - our show Cocker spaniels many years ago had a tendency to podginess. Thankfully they all lived to a good age regardless.
Are Labradors naturally cunning dogs with an innate ability to snaffle nosh when backs are turned ? Or do their big brown eyes overcome their owners every time ?
