Is it normal for my bitch to take an interest in other dogs after mating? She has been flirting with my Weim (he is neutered) is this normal or does it mean she isnt pregnant?

Bitches will happily mate with any dog when they're in season. The pups in a litter can be sired by many different dogs if the opportunity arises. You still need to keep her safe from all unwanted attention till her season has finished.

Yes, perfectly normal, they will flirt outrageously at the time they are standing, so watch her like a hawk, little floozy.

If she's still standing you could take her back to your stud.

the third season she was still standing at 18 days to anything !!!
we decided to take her back to the breeder and it worked she
