Reproduction Flashcards
Reasons NOT to breed
Questionable temperment
Poor mothering ability
Genetic defects
Poor quality animal
Overpopulation
Supporting Spaying & Neutering
Increased risk of pyometra
Prostasis and prostatic hyperplasia
Neutering early in lofe decreases the risk of mammary tumors ad nearly eliminates the chance of occurence, uterine, ovarian, and testicular neoplasms
Puberty
6-24 months
puberty for large dogs
18-24 months or older
Puberty in small breeds
6-10 months of age
Ideal breeding age
Wait until 2nd or 3rd estrous cycle for first breeding(too early she will shift focus to babies and stunt her growth)
ideal breeding age is 2-6 years of age
NO geriatric pregnancies
Produce ova (eggs) and reproductive hormones (estrogen and progesterone )
Ovaries (2)
small thin tubes that transport ova fro the ovaries to the uterus. Fertilization occurs near the end of oviducts
Oviducts
Muscualr Hollow y shaped organ consisting of 2 horns , a short body, neck, and cervix
Uterus
fibrous/ muscualr structure that serves as the channel between the uterus and vagina
Cervix
Time of reprofuctive Rest
2-10 MONTHS
ANESTRUS
ESTROUS CYCLE
ANESTRUS
PROESTRUS
ESTRUS
DIESTRUS
ESTRUS (9 DAYS)
Flaccid vulva
estrogen levels have dropped
progesterone is high
Red and profuse discharge to brown and scnty
accepts maale
Flagging: deviates tail and moves hips to side
LH
comes from pituatary
60-80 days
progesterone is bieng produced
progesterone increases for first 30 days then declines slowly unless pregnant
dissapearance of discharge ;vulva is a normal size
some mammary developmemt
no longer shows sexual behavior
Diestrus
