I have a hunt coming up first of January that starts with a half day on Friday and then Saturday/Sunday are 8-10 hrs of hunting. Then two day break for travel and then 3 days in a row of 8-10 hrs hunting. My dog’s are in really good shape but this really drains them of energy at the end of the day. Have any of you seen a big difference with energy supplements and what ones would you suggest? I feed 31/22 food currently.
