Hi, thanks for using Petco Pet Education Center, formerly Petcoach! I recommend starting early weaning on bottle fed puppies as formula can cause GI problems (diarrhea and/or constipation). I would start with some canned puppy food mixed with formula and offer it three times per day and continue bottle feeding. If the puppy eats the mixture well at each meal then I would only bottle feed 3-4 times per day. If he is slow to eat the puppy food then I would continue bottle feeding every 3-4 HOURS. Decrease the bottle feedings each week as you increase the puppy food feedings. By 5 weeks I would start offering dry mixed with canned and stop all bottle feedings by 6 weeks. How much you feed of the formula at each feeding depends on the brand you are feeding. Usually the can/box tells you the volume. You can repost with the brand and I can try to helps you Good luck!
