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.
#5. If you want a clear idea as to how big your border collie will be, check out their parents if possible. I've seen 75lb border collies, I've seen 50lb border collies, and I've seen 23 lb border collies...I think most fall in the 35-45lb range, but there are exceptions to the rule as always... Ido is 28lbs...
