You know alot of the stuff mentioned in that article didn't pertain to us either. He get's alot of exercise and love so i'm assuming stress isn't part of it.
He's pretty happy go lucky type of dog. As other beagle owner's know.. they can be compulsive eaters.. and he is. When we put the food down during feeding time I have taught him to wait until I say it's okay but once I do he act's like he has never eaten in his entire life. He can kill a cup of dry within seconds.
Beagles also gain weight very easly so we only feed him one cup twice a day, is it starvation? I don't think so because he weights 38lb's! When the typical beagle should only weight around 27lbs.
He turned a year old in May so he's still a pup but full grown and well mannered around the house for his age. He likes to jump up to greet people but listen's when we tell him to get down. Other then that he's good... doesn't chew furniture or anything else.
He is however always on the hunt for something (or anything) to eat. Does not matter what... grass, sticks, snails, rocks, leafs.. .literally anything he finds he eats.
