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.
Collie Color: The two base colors in collies are sable and black & tan. Most of us know, that in collies, sable is dominant and tri-color recessive. A puppy inherits one color allele from each parent. An allele is an alternate form of a gene. Therefore, if a collie inherits a dominant sable allele from each parent, he/she is a pure for sable (homozygous for sable). On the other hand, if a recessive black & tan color allele is contributed by each parent, the collie will be a tri-color (homozygous for black & tan).
