Therefore, it was concluded that high levels of estrogen correlated with an improvement in psoriasis, whereas progesterone levels did not correlate with psoriatic change [ 13 ]. Many studies investigated the relationship between hormones and psoriasis; it has been observed that worsening of symptoms occurs when estrogen and progesterone levels drop postpartum, prior to menses, and at menopause, while most patients receiving hormone therapy around menopause noted no change in their condition [ 3947 — 50 ]. Estrogens have been shown to stimulate B-cell mediated immunity while suppressing T-cell mediated immunity; progesterone, being primarily immunosuppressive, downregulates the T-cell proliferative response and has been shown to be the key factor in immunosuppression [ 51 — 56 ]. Therefore, it has been hypothesized that high levels of progesterone would correlate with improvement of psoriatic symptoms [ 46 ].

When they are young, they learn much and what is learned has a lasting impact. Even sexual patterns, which emerge as puppies mature, can be affected by early experience. All dogs, regardless of breed, pass through various stages as they grow and develop, physically, mentally, and psychologically.

Psychologists use the term critical period to describe a specific time in a dog's life when certain experiences have a lasting effect upon their psychological development.

Puppy Toddlers 3 - 6 Weeks During the Toddler period, puppies emerge on their own from the litter. They venture into the surrounding environment.

While playing, they practice different body postures, learning what the postures mean and how they affect their mother and litter mates. They learn what it is like to bite and be bitten, what barking and other vocalizations mean and how to make and use them to establish social relationships with other dogs.

Such learning and activity tempers their own biting and vocalizing. From the age of five weeks, the mother teaches her puppies basic manners. They learn to be submissive to her leadership and what behaviors are acceptable. If necessary, she growls, snarls, or snaps at them as a form of discipline.

When weaning the litter, for instance, the mother will discipline her puppies so that they will leave her alone. Because the mother disciplines them in a way that they clearly understand, after a few repetitions, the puppies will respond to a mere glare from her.

If a pup has not learned to accept leadership and discipline in its early interactions with dogs, its training will be more difficult. Puppies that are removed from the nest too early tend to be nervous, more prone to barking and biting, and less responsive to discipline. Often they are aggressive with other dogs.

Generally speaking, a puppy taken away from it's mother and litter mates before seven weeks of age, may not realize its full potential as a dog and companion. To maximize the mental and psychological development of puppies, they must remain in the nest with their mother and litter mates until seven weeks of age.

Socialization Period 7 - 12 Weeks It is at this age that rapid learning occurs. At seven weeks, puppies can learn and what they learn will have a lasting impact. Everything he comes in contact with will make a lasting impression upon him as it never will again.
