Reproductive  Scottish Terrier

The first sign that a bitch is in season is a red discharge, this my increase during the first week. The discharge will then change colour to yellow which will last for another week. At this time the vulva will also swell, and the female is now ready to mate.

Around the second week or so ovulation occurs, this is the critical period for her to mate. The female will have many eggs know as Gametes, each egg is surrounded by a wall, that only the strongest sperm will penetrate and fertilize the egg.
