Labrador Retriever Central!

So I work at a dog kennel. And we offer, training, boarding, grooming, wellness and of course Doggy daycare. And as animal care attendants we rotate working in daycare. I was out there a good two to three hours today with all the dogs. And I noticed that there were A lot of labs there. And they all were different. First there was Jade. She is very loving, sweet and calm as can be. Very well bred in my opinion. The ideal lab. She was a good size, not too thin or too fat. She was a beautiful yellow color and had gorgeous hazel eyes. I wish all labs were like her. Than there was Cooper. He is a freaking Mac truck. I asked his owner how much he weighs, and she said just a little over a hundred pounds! And almost white in color. He looks innocent but he is a huge jackass! Very dominant. He is always humping the other dogs to show he is more dominant then they are. And whenever someone walks by the daycare yard he is always barking very aggressively. And he is always in everyone's business. Than there was Horatio. He is a chocolate lab. Very tall and very skinny. He was very hyper. He would never sit down and rest. At least Cooper will take naps every now and than. Than there was polo. She is a black lab. She is very very short. Almost looks like a really fat puppy. But she is full grown. She has a personality much like Cooper's. I was kidding with my Co Worker saying that I think she is related to Cooper. Than it got me thinking. Why do People breed dogs with these traits. Not only are they not visually appealing (which is the least important thing to me)But they are idiotic and their personalities are horrible. Not really good family dogs like the lab's portrayed in the good ol' days. I am really against breeding these days since the shelters are packed with dogs that need homes. But if you insist on breeding, why can't you breed decent quality dogs like Jade (dog mentioned above). Than there are Labradoodles! Ohhh the horror! For those of you who do not know what a Labradoodle is. Its a lab, poodle cross. Its considered a "designer dog" But ill get into that another day.
