my bitch is 2 years old and is coming into season. she had a bit of light discharge yesterday and her vulva is enlarging. today it is darker. brown in colour .at what interval in her season is the best time for her to concieve. i have bred cats before but this is my first time for dogs.so im not quite sure about the way things work and the time scale of it all .any pointers would be much appreciated .thankyou all for reading my thread. andy
