If I were you Elpseth I would put her under house arrest soon, I know of several bitches who have produced puppies when a dog just jumps on the girls back and gets pulled off and when she is hot and ready she may even bog off to look for a male, my old Collie would do that but then she was a hussy. I'm afraid my girls stop getting walks around 9 days until they have finished just in case you never know what dogs are around, up to you but that's my opinion, to tire them out it's plenty of hide and seek games in the house and garden.
