AKC BREED STANDARD FOR LABRADOR RETRIEVER: (Not for a miniature lab)
"Size, Proportion and Substance: Size-The height at the withers for a dog is 22½ to 24½ inches; for a bitch is 21½ to 23½ inches. Any variance greater than ½ inch above or below these heights is a disqualification. Approximate weight of dogs and bitches in working condition: dogs 65 to 80 pounds; bitches 55 to 70 pounds. The minimum height ranges set forth in the paragraph above shall not apply to dogs or bitches under twelve months of age. Proportion-Short-coupled; length from the point of the shoulder to the point of the rump is equal to or slightly longer than the distance from the withers to the ground. Distance from the elbow to the ground should be equal to one half of the height at the withers. The brisket should extend to the elbows, but not perceptibly deeper. The body must be of sufficient length to permit a straight, free and efficient stride; but the dog should never appear low and long or tall and leggy in outline. Substance and bone proportionate to the overall dog. Light, "weedy" individuals are definitely incorrect; equally objectionable are cloddy lumbering specimens. Labrador Retrievers shall be shown in working condition well-muscled and without excess fat."
HAVING SAID THAT:
How many of you guys have met a 80-120lb lab? The purpose of our Miniature Lab program is to "prevent" a giant lab. It is also to CUT down on the Lab "high" energy level. Did you realize that a lab energy level (according to AKC) is rated as "High" (level 5) energy. Did you know that the Jack Russell Terrier is also rated (by AKC) as a level 5? Now, high energy is good if you actually plan to WORK your dog! If you want a hunter, that is AWESOME! But if you plan to have an apartment pet.....high energy can cause a LOT of problems. ;o(
MINIATURE LAB ENERGY: 3 (on average)
PURE BRED LAB ENERGY: 5 (on average)
Please be aware that the 24" lab breed standard is NOT to the top of the dogs head. It is at the dogs shoulder (wither) with the head being yet taller.
