Needless to say, this line is bred for intelligence, gentleness of temperament, tolerance, and a balance of energy with composure. They are as happy with a romp through the park as they are with a quiet evening at the hearth. No matter what differences in lines, all Labrador Retrievers are expected to maintain the characteristics that originally made them working dogs: stamina, energy, strength, and the ability to retrieve dependably, along with balanced structure and vitality.
A nice Lab puppy can usually be purchased for $700 to $1,500. For this price you should expect the puppies to have been raised in a clean environment, from parents with health clearances and show or field championships to prove that they are good specimens of the breed. Puppies have been temperament tested, vetted, dewormed, and socialized to give them a healthy, confident start in life.
It has been shown that out of all dog breeds, it is the Labrador Retriever that is most likely to be obese. In a 2016 published study it was shown that out of 310 Labradors, most were missing all or parts of the POMC gene. This gene plays a part in appetite regulation as well as indication of the amount of one's stored fat. The study concluded that the absence of that gene had a significant impact on Labrador weight and appetite. The POMC gene mutation is present in only one other breed – the Flat-Coated Retriever.
