The moment that a puppy was born, his fed him and took care of him; quite often without any form of effort on the puppy’s part. This will continue until the puppy is about 6 or so weeks old during which time his only source of nutrition is his mother’s milk. By the age of 6 weeks, the mother will discontinue feeding the puppy milk and instead turn over the job of feeding the puppy to you, the mother puppy’s trusted master. You will probably want to get your dog a nylabone wishbone to help with their desire to chew.
Some serious growth occurs during this first 6 week period. Your puppy enters the world with his eyes sealed shut with mucous and will stay shut for several weeks before they first begin to open and look upon the world around him. Furthermore, your puppy will gain some serious weight during this time which of course is dependent upon his actual breed and can range anywhere from 15 to over 40 times the weight the puppy was at birth.
The puppy will need plenty of energy and nutrients to get himself through this fast period of growth, but by the time that the puppy matures into a full grown adult dog, his energy levels will begin to decrease and his need for nutrients will decrease as well.
As this maturing begins to occur, it is a physical sign to you, his master that you will need to change his diet as the needs in food will be changing drastically. The food that was needed to support the puppy’s fast growth will no longer support him once he matures. As his needs change, so to should his diet to compensate for the changes. You will also want to get your dog some cheap dog clothes such as some dog sweaters to keep them warm.
As an adult dog, he will need certain nutrients to continue to live healthy and these nutrients are found only in the food that the dog eats. These nutrients include things like protein, carbohydrates, minerals, vitamins as well as fats and water. Meeting the minimum daily requirement that your dog needs is solely your responsibility and these requirements are based on the stages in life that the dog is in. The life stages of a dog include the growth stage, maintenance stage, a work stage, a pregnancy stage if it is a female as well as a lactation stage.
