=== Pseudopregnancy ===
=== Pseudopregnancy ===
* Almost all bitches show some evidence of pseudopregnancy during metoestrus.
** Covert pseudopregnancy: where the bitch is in metoestrus, but shows little or no signs.
** Overt pseudopregnancy: where the bitch shows signs ranging from slight mammary development and lactogenesis to mock-parturition with nesting, loss of appetite, straining, emotional attachment to inanimate objects and heavy lactation.
* There is no difference in progesterone concentrations in bitches with or without pseudopregnancy.
* Prolactin is probably responsible for initiating the changes.
