Still swim my Spanish for the first 5 weeks of pregnancy, it's never done them any harm. You need to be careful re the water though and make sure that it's safe. If your dogs fit and active I'd continue what you usually do in moderation. Took one of my Spanish to her first workig test when she was 5 weeks gone and she loved it and so did the pups first time ever that I've felt pups kick at 5 weeks and it's never happened since :d
Good luck on you pups :d
