How Your Thyroid Works. Controlling hormones essential to your metabolism. Your thyroid gland is a small gland, normally weighing less than one ounce, located in the front of the neck. It is made up of two halves, called lobes, that lie along the windpipe (trachea) and are joined together by a narrow band of thyroid tissue, known as the isthmus.
What is the average weight of a Border Collie? 30-40 lbs for a female (13.5-18 kg) and 40-60 lbs for a male (18-27 kg) Though there will always be exceptions to this (i.e. larger or smaller dogs), the large majority of Border Collies fall into this range. The breed as a whole is a medium-sized breed.
According to American Kennel Club standards, the border collie's height ranges between 18 and 22 inches at the shoulder, while the Labrador retriever's height ranges between 21.5 to 24.5 inches. The Lab's weight runs between 55 and 75 pounds, while the border collie ranges between 30 and 45 pounds. In both breeds, males are larger than females. Your borador should fall somewhere in the middle of the two parent breeds, almost as tall as but thinner than the Lab.
