Puppies around the age of two weeks old start to experience teething. Teething is the process by which a puppy's deciduous teeth come in and then fall out to make way for their permanent teeth. By 5–6 weeks of life, all of the deciduous teeth have come in, puppies will grow in a set of 28 deciduous teeth or needle teeth.
Like humans, puppies are born toothless, then grow deciduous baby teeth which fall out and are replaced by adult teeth. However, it all happens a whole lot faster in canines than in humans.
The other common system defines "dog years" to be the actual calendar years (365 days each) of a dog's life, and "human years" to be the equivalent age of a human being. [2] By this terminology, the age of a 6-year-old dog is described as 6 dog years or 40–50 human years, a reversal from the previous definition.

In humans, the upper canine teeth (popularly called eye teeth, from their position under the eyes [1]) are larger and longer than the lower, and usually present a distinct basal ridge. Eruption typically occurs between the ages of eleven and twelve years for upper canines and between nine and ten years for lower canines.
The teeth in the upper and lower jaws in mammals have evolved a close-fitting relationship such that they operate together as a unit. "They 'occlude', that is, the chewing surfaces of the teeth are so constructed that the upper and lower teeth are able to fit precisely together, cutting, crushing, grinding or tearing the food caught between."
