Hi I really want to breed my large breed bitch but dont know what day in season she is in. My vets are being very unhelpful and dont know where to turn. I have decided to just try to mate her with the stud out of luck if there are no puppies then so be it.

So could someone tell me when I should take her.
is there anything to look out for
is earlier better than later and then keep taking back until she stops growling at him.

If you don't know when she came in season (though surely whoever was looking after her must have seen) then I think you would be better off waiting until the next season.

After all you will be tying up the stud dog owner for much longer if you are trying now, will cost you loads more in fuel if you can't stay away with her or board her with the stud.

In the normal event you'd be looking at up to a week for the mating period, like this it could be two..

I would leave it too as you seem very disorganised.  These things should be planned well ahead.  Have you a stud dog lined up etc?

is earlier better than later and then keep taking back until she stops growling at him - I would be questioning her suitability as a brood bitch and pitying the poor stud dog and his owner!!

Agree with ells bells here.  Not the way to go! 

Animalmagic, you already have a quite similar thread running - could you continue with that thread please rather than start a new one. Thanks
