The puppy stage lasts until six to eighteen months. During this time, they harbor most of their life milestones. For example, touch and smell develop right after birth. Between two and four weeks, puppies begin to stand, bark, walk a little bit, and wag their tail. During weeks three through twelve, socialization needs to happen between other canines and humans. They also gain full use of all their senses, and can experience real fear to everyday objects. The adolescent phase starts right after puppyhood ends, between six and eighteen months. Which includes the teething process as well as ranking of the pack. Pack mentality is extremely important in not only one specific breed, but all Canidae. Canines will have the most influence on their behavior by fellow pack members. Sexual behavior will also start occurring during the adolescent time, if the dog is not spayed or neutered. Adulthood is considered twelve months of age until three or six years. After that is the geriatric (senior) stage that or which, lasts between six years old and until the dog passes away (Stages of puppy development, …show more content…
There are four phases of reproduction that is universal to canine’s. If the female dog is not spayed, they will go into heat every five to nine months. The first phase, the proestrus stage, lasts about nine days. Between these days the female (bitch) starts releasing pheromones to attract males (stud or sire) and ends when the female becomes receptive to the male. Phase two, the estrus phase is the time a female is willing to breed. It lasts between seven to nine days, but could last up to twenty. Ovulation in the female occurs on the second day of estrus or the twelfth day of the heat cycle. Veterinarians can do a vaginal cytology on the female during this time to gauge when the ovulation will start. The third phase diestrus or also known as the luteal phase begins. During the luteal phase, the bitch will no longer stand for the stud. If she becomes pregnant, she will stay pregnant for 56-58 days. The last phase, anestrus, is the time where the female is back to normal life. Her progesterone levels are lowered to their original state, and lasts around 130-150 days. C-sections have become most popular throughout the years due to breeders taking the birth plan into their hands. Many Staffordshire Bull Terriers do have C-sections, but not for reasons one may think.
