When faced with this situation, i had a dog that was possible in the best shape of her life and one of the best keeps i've done. I could say the dog was close or a little over 90%, and when collected the fit, i thought i would just rest her for 3 weeks and then find another swamp to chase some boars. Well what i end up doing was giving her 3 days off and then walking and running her lightly when i say lightly all i did was take a ball and throw it out to her for about hour or so.. did that for 3 days then rested her another 2 days.. then ball time for 2 days rested her for about 4 days then ball for 2 days and rested her for 5 days.. about a month had passed and she was still looking excellent and worked her way down to normal but still premium shape for most chain dogs.. Well when her # got called again i started working her and it was probably the best 3 first weeks i ever had because while she wasnt at peak, she was still in tip top shape but had time to flush her body out and rest down but remain in shape, and she was showing me that she could hit another level of training and i was concerned she would peak out too early but an old friend said, no she won't peak she just showing you how much better she can when you are doing more.. Well come time and it was the best 54 mins i ever seen and the gyp literally never blew one time.. (will admit i added jack's spring pole sessions) in my own keep and it worked out great.. If you're dog is in great shape, then a few cool down days with some light work over time won't hurt them while you still looking for a swamp to run in.. Also not sure what ingredients you use in your keep, but if you using things that are extreme on the body, then you might need a couple weeks to flush their body. Also not sure how much work your dogs get when they not in keep but a keep on a dog that is 15lbs over weight and gets work once a month is a little more stressful on a dog then a dog who gets some typical work throughout their lives. Have some good land where I'm at and dogs get some free run here, and others get a few mins on the mills inbetween walks so that for one they used to their tools and also keep some work in them.. I like dogs who enjoy working, whether its a slat, a carpet, free running pulling or swimming..
