How is the Great Dane’s Height Measured?

   It is challenging to measure Great Dane’s height with a ruler due to his huge size. Small dogs are runny, so keeping them in place to measure their height is hard. Luckily, weight is more crucial than height to keep an eye on progress and development. So, what is the best way to do this?

   Usually, Great Danes are measured from the end of their paws and up to the corner of their perky ears. But the right method is to measure them from their paw’s end to the high end of their shoulder blades. If you are measuring your Great Dane’s height at home, measure him just like a human child by standing against the wall.

   The one thing is that your pooch will not stand, so give him the treat to stay quiet. Take measurements from the peak of the withers between the shoulder blades because it is the tallest point of a dog or horse’s body. After making that mark on a wall, measure from the floor to this spot and you are done.
