3 months
How can spaying cause a persistent pseudopregnancy?
If you spay a dog in the luteal phase and not in an oestrus they will have high levels of progesterone currently being produced
Spaying causes a dramatic rapid fall in p4 causing the pituitary to respond and produce more prolactin
Causes iatrogenic pseudopregnancy
