How to know a dog’s age?
Normally if you are the owner of the dog you will always know the approximate age of your dog. But if you are going to get an older dog you may need to ascertain the age of the dog.
In other animals age can be determined fairly accurately by examining teeth of the animal. But this procedure of dental examination is not very reliable for determining a dog’s age and can only give you a rough estimate.
Another method is checking dog’s eye. Actually in this method the color of the pupil is checked.
Young dog’s pupil is shiny and deep colored. With passing years the color of the pupil keeps changing and becomes lighter. It is more reliable method than teeth checking but require some experience on the part of the examiner.
But this procedure is not very effective if the dog very old because often there may be some health conditions which influence color of the pupil.
