Puppy Care Stages: Newborn to 48 Weeks

All about caring for your young dog.

puppy care

The rate at which a puppy grows to maturity is somewhat dependent on the breed.

Some dogs retain a "puppyish" disposition well into their dotage, and some youngish dogs are almost cat-like in their unflappability.

There are, however, some similarities among all breeds.

Here are the typical stages of puppy life during the first 48 weeks.

  • Newborn to three weeks -- silent senses
  • For the first three weeks of life, a puppy is almost devoid of senses. Its eyes, ears and nose don't begin to work properly until the third week. During this period, puppies sleep most of the time and there's nothing wrong with that. Sleep is vital for a newborn puppy's development.

  • Three to eight weeks -- socializing with the siblings
  • The puppy's senses awaken. It should be able to walk by the fourth week. Mother begins weaning the pups and starts teaching discipline. The puppy socializes with its siblings and learns bite inhibition through puppy play-biting. The owner or care provider can begin to introduce solid food in the fourth week. It is vital that the owner or care provider not separate the puppy from its mother for extended periods of time during the day. A puppy should remain with its litter mates till it is at least seven or eight weeks old, although some experts recommend as long as 12 weeks. This period is crucial for establishing a dog's identity and insuring its life-long stability.

  • Eight to 12 weeks -- fear of the new
  • Physical coordination is refined during this time. A puppy placed in a new home during this period will be apprehensive about almost everything in that home at first. The owner or care provider must attempt to make the puppy's experiences during this period as positive and comforting as possible because puppies at this stage are hypersensitive to upsetting incidents. Housebreaking can begin at eight weeks and training by nine weeks.

  • 12 to 24 weeks -- chewing everything in sight
  • The first permanent teeth make their appearance and may seem like a mixed blessing. The puppy will need to be provided with suitable items to gnaw upon and will need to be shown (either ceaselessly or endlessly) the difference between suitable and unsuitable in the realm of gnawable items. The puppy will challenge the owner's or care provider's authority during this period. In their natural state, dogs prefer a strong leader. Professional training can help a dog understand what is expected of him and can help an owner curb any wimpy tendencies.

  • 24 to 48 weeks ?- teenage doghood
  • Challenges to the authority of the owner or pet sitter will continue during this span. Repeat the puppy owner's mantra, which is "No!" (please notice the exclamation point). Spaying or neutering curbs a "teenage" dog's tendency to want to spend lots of quality time with canines of the opposite sex. Actually, what spaying or neutering really does is change a dog's definition of what spending quality time with canines of the opposite sex really means. Adolescent dogs of all breeds need lots of exercise, not just naturally large breeds.

Raising a mannerly, well adjusted dog is all about staying attuned to his signals and sensitivities and not being afraid to take control and assert authority.

I have to agree with Kerrie on a couple of points. While spay/neuter WILL curb unwanted behaviors such as marking, "humping", and aggressiveness...if it is done early, but once a dog starts a behavior, there is little surgery will do to correct it. It will also not "automatically" stop unwanted attention to the opposite sex. A male, for example, (especially if neutered after 6 months) will still have testosterone for up to 4-5 months post-op.

No puppy should start house breaking by 8 weeks of age because NO puppy should be removed from the litter before 9 weeks...EVER. I would not trust a breeder that would do it before then.

In reality, large breed dogs do not require more exercise than small breeds. Terrier types and others with high energy certainly require more exercise as do certain breeds such as Border Collies and Huskies. These particular types are more prone to becoming bored, this can lead to serious unwanted behaviors. Large breeds ( such as Rottweilers and GSDs) can be prone to a condition called panosteitis. Due to their rapid growth bones become painful and this can lead to lameness. It generally affects puppies between 6-18 months of age. This is certainly true of giant breeds such as Great Danes. Exercise cannot be generalized, as it is entirely specific to the dog and his/her breed, not just "small or large".

Seriously the worse article ever about dogs...
NO! this will not fix anything and dogs don't speak English. So how are they suppose to know what No means?
Redirect the puppies attention away from the whatever is inticing them. Use a treat or a toy to do this with.
Also if you are having problems with a dog, neutering or spaying will not fix everything. Not even leg humping. A good trainer will help correct behavior problems. Not spaying and neutering, that only keeps unwanted puppies at bay.

Also there will be a second fear period when the puppy reaches adolesence. This one will be just as important as the first one. Maybe more so.
What are the qualifications of the writer? Can't you find a professional dog trainer to write for the pet care section about dogs? Or a behaviorist?
