Female dog allows your dog and conception may be occurred. From then on vaginal discharge is dark yellow. Usually, this stage takes four- thirteen days. Female dogs allows male dog to reproduce together with her in those times.

.....sorry I ought to have added....if he has been neutered recently, then don't risk it. He could still have residual sperm. If it's a while ago, that's ok.
Yes, beetches is a bad word here!! (not really I think!)
Those two are going to produce puppies quicker than a magician produces rabbits out of a hat soon! Even if that's what you want, then I would definitely wait awhile. She is not fully mature yet, too young to produce a healthy litter, and it would be a terrible strain on her at her age. I think it is best to wait until she is 2 years old.
If you don't want this hassle every six months, (that's how fequently a female comes in estrus)and you do not want to breed her then the best thing is to get her spayed. If your male dog has been neutered, then whatever they do can't do any harm. But if he hasn't.....watch out!
Okay, I see that this site does not allow the use of the dog breeders' usual word for an adult female canine. No offense intended.
Whether you need to separate them depends on whether Luke has been neutered or is intact. Since you're asking the question, I guess he is intact. But since you don't say whether he is or not, I thought maybe someone should point out the obvious.
It would be a bad idea for Lola to get pregnant at nine months. She is not even grown up. It would be kind of like a 12 or 13 year-old girl getting pregnant.
The responsible breeders that I know wait until their ******* are at least two years old and have been certified by OFA as being free of hip dysplasia. Sometimes they wait longer, if the ***** is slow-maturing or they are looking for just the right sire to complement her genes.
Are you trying to breed them? If Lola's in heat, she can get pregnant with Luke around during this time. Check out this article. It has quite a bit of information. Good luck!
