How soon after mating will my bitch stop bleeding?

There are four phases in a bitch's cycle.
1. Pro-estrus: The most noticeable phase, usually some swelling of the vulva plus a clear discharge which then becomes bloody. This may only be spotty and most bitches keep themselves as clean as they can. Some may have a heavy discharge and no swelling, others may have little discharge but heavy swelling. This can last from 8 to 13 days.

2. Estrus: Is when normally the bleeding has stopped. The vulva is less turgid but still swollen and there maybe a clear or straw-colored discharge NOW is when the bitch is most likely open and willing to be bred and may seek out dogs and usually accept them. It lasts from 4 to 7 days.

3. Metestrus: Is when she will be starting to either grow puppies from breeding, may have a false pregnancy or not. 6 to 10 weeks for this.

4. Anestrus: which lasts about 15 weeks is the quiet period of variable duration when there is no activity in the bitch's reproductive tract.

If your bitch was successfully bred...and you wanted her to be...she should no longer be bleeding if you have entered stage three...Metestrus. If she's still bleeding a few days after the breeding, or if the discharge has gone from the clear or straw color BACK TO the more thick, red blood color...you'd better take her to the vet now. It's possible that the dog tore something IN her and there could be a problem.

Can be up to 12 weeks, just make sure it is prpoer red, more pussy kinda colour can mean infection and you will need to take her to the vet!

my bitch is spotting 3 days after being bred. they are rottweilers and are very big dogs? this is her 1st mating? i've never experienced bleeding after being bred? could there be a problem. cassie is 30 months old and the stud is the same age. this was the 1st time for both. the stud wouldn't mate with her for hours, i've also never experienced this. were they too young to breed? i have had 3 other females and bred all 3 at the same age. just a little worried at this point. she is also very calm now and content it seems. she is a great dog and only want the best for her, i am experienced breeder and a responsible one at that. i was very careful in picking her stud. they both have all shots and were seen by there vets before breeding.
