How to find out the age of a puppy
A younger puppy is roundish and cuddly looking up to about 2 or 3 months old, smells sweetly good, is awkward and clumsy in movements, and frequently may trip or stumble over him/herself. His concentration is on getting around in his new world! A puppy around 4 to 5 months old looks like a gangly adolescent and seems all legs and big ears. He still must grow into his head, ears, and paws! He still has the fuzzy puppy hair. After about 6 or 7 months, a young dog may begin to look more like an adult, perhaps of slighter built, with a sleek and glossy coat, flexible body, and bright eyes with white teeth. As they grow older they appear less flexible, become stockier (or put on weight), the whites of the eyes may lose some of their whiteness, and the teeth gather plaque. As they grow even older, seniors start to gray somewhat (especially around the muzzle and face). Real, real old fellows may become thin and have bad breath! Cataracts are common. Those are the basic stages of youth to old age.
Their teeth start coming in at 5ish weeks. By 6 weeks they should have their teeth enough to eat mashed up kibble with water. Their teeth will be very white, sharp and small. The older they get, the more their teeth get plaque, tarter and yellowed, much like humans.
yeah what chihuahuaaddict said take your pup to the vet the vet will look at his teeth and they will tell you what age is is!! :)
Well, at about 4 weeks a puppy still has a glazed over look in it's eyes... but thats the only way I know how to tell :)
A vet would be able to tell you for sure, by looking at the puppy's teeth!
