It can be difficult to predict the rate at which they will grow, but, they will still grow quickly during their first year of life. This is much lighter because of their smaller size and legs. The Miniature lab’s weight range is approximately 35 to 50 pounds vs. A female should stand at 21.5 to 23.5 inches tall.Īlso miniatures weigh about 20 to 40 pounds less than other types of labs. However, for miniatures with extreme cases of SD1 this can be a short as 17 inches.Īccording to the Labrador Retriever Club’s official breed standard a male should be 22.5 to 24.5 inches tall. A Miniature lab can stand from 19 to 22.5 inches tall. However, they are by no means considered a small dog.Ī Mini lab is between two to three inches shorter than other labs. The degree to which they experience dwarfism will be unique to each pup. Puppies who inherit the recessive dwarfism gene will not grow as much as their litter mates. How Small Does A Miniature Labrador Get? Miniature Labrador (left) vs Lab (right) To make sure that a puppy has not inherited dwarfism, the breeder must be able to provide proof that the parents do not carry the genes for dwarfism. Puppies who inherit this condition are more prone to develop health issues, have a lower quality of life and shorter lifespan.īreeders who advertise Miniature labs are likely not reputable. This breeding practice has brought about many ethical concerns. The problem with this breeding practice is that it increases the likelihood of Labradors inheriting the recessive SD1 and SD2 genes for dwarfism. However, large dog breeds are not meant to be shrunk down. The first Miniature was reported in 2007. Some dogs can naturally be smaller, but this is by chance. This has led to some breeders trying to miniaturize them. The temperament of the Labrador makes them a popular family dog, but their size can be a bit much for some. Some successful examples of this are the Toy Poodle and Teacup Pomeranian. The miniaturization trend has led to breeders selectively breeding the runts of each litter. Their smaller size makes them perfect for apartments and small children. Toy and teacup dog breeds have become extremely popular as many prospective owners are searching for dogs that suit their lifestyle. Miniature labs with pituitary dwarfism have shorter legs just like those with the SD2 defect. This defect decreases the release of growth hormones and limits the growth of long bones. It is caused by a defect in the production of growth hormones. Pituitary dwarfism is rarer than the SD1 and SD2 genetic disorders. They will have the same broad head, “otter” tail, and short and dense waterproof coat in either silver, black, chocolate or yellow.Īnother possible form of dwarfism is called pituitary dwarfism. The main difference is that they will have shorter legs. Labs with SD2 will look just like a healthy, standard Labrador. This type of dwarfism is known as a mild form of dwarfism and is the most common. bowed knees or bent knees) or health complications. This genetic mutation results in shorter legs, but it does not cause any deformities in the legs (e.g. SD2 is a form of dwarfism that stops the growth of long bones. Hip dysplasia causes pain and lameness due to swollen joints, bowed knees, turned out feet and a low slung back. Miniature Labradors with SD1 will have very large heads and develop hip dysplasia. It also causes defects in the development of the bones, skeleton, cartilage, and connective tissue ( i.e. This genetic condition causes malformed and/or bent legs. SD1 is a genetic disorder that has many dangerous health complications. These genes can also affect Labradoodles, but this is not how Mini Labradoodles are bred. These are known as skeletal dysplasia 1 and 2 ( i.e. There are two genes that are mainly responsible for dwarfism. Usually miniatures will only be two to three inches shorter than a full sized Labrador. Sometimes this difference is not so obvious. The main difference between these Labradors is that they have shorter legs. Miniature Labradors are born from two purebred Labrador parents who both carry the recessive dwarfism gene. However, they are very rare because they are caused by a genetic condition called dwarfism. How Small Does A Miniature Labrador Get?.
