No need to apologize I was more than happy to repost. And yes we have our dogs on a feeding schedule. When Ace was a pup I fed four small meals a day at the same times each day, then a few months later went to three times a day at the same time each day, then at about 8 months twice a day at the same time, once in the morning and then a larger meal in the evening. Now Ace is fed one large meal in the evening, always at approximately the same time. He may also get a little something in the morning and treats off an on. But I was way more precise when he was a young pup so that his bowels would be regulated at about the same time each day. Now it doesn't seem to affect him much. He usually "does his business" about the same times each day regardless at what times we may treat him, but his main meal is always at approximately 6:45 pm each evening
Also while you pet is still a pup, always take him out about 15 minutes or so after eating or sooner if he shows signs he needs to go outside. But regardless as a pup, feed him at the same times each day and take him out a few minutes after eating. When you play with your pup or he otherwise gets excited, then after playing take him outside for a few minutes as well. You will be able to recognize the tell tell signs when you take him out if he needs to go. Not every time you take him out after eating or playing will he poop but he will eventually develop a rhythm and go at about the same times each day when you take him out. But while he is still a young pup he hasn't developed that rhythm yet so you have to take him out at the times I have suggested in these posts. But eventually a rhythm will be acquired and you will know when his main times are to "relieve" himself. I can just about guarantee it will work out for you both. Get on the schedule and stick with it, its hard work to begin with and tiring but it will be well worth it in the long run
