If you ever wondered how a dog breeder knows a female is ready to be bred....just look at their bloodshot eyes, sleep deprivation is a big clue. Apparently the egg dropped last night around 4am and the boys began howling and whining to let me know that we have fertile girls in the house. No need for progesterone testing around this place to tell if now is the time for making puppies....Grrrrrrr I need to buy new ear plugs to survive the next few days.
