Twice a day. I feel that if you time ur feedings correctly bloat won't be an issue. Feed in am at 7 unless we are training and its a weekend. then I feed as soon as I get up and then by time I get ready and drive an hour to training grounds he's good to go. Might volunteer to run last if I feel I didn't get a full 2 hours in. If its a short training session and in the summer it usually is then ill hold off till we get back around 11 am.
In the afternoon come home train till 630 or 7 feed at 9. If not training feed when I come home which lets him know he's got the afternoon off.
Cup and a half in am 2 cups in pm. Victor hi pro plus. Up till he was 6 months it was 3 times a day when I could. Course feeding eukanuba large breed puppy and its high corn content he was supposed to be getting 6 cups a day. Good no corn food requires less intake to get proper amount of nutrients
