Hello! Do you let your dog graze all day and eat when they decide they are hungry or do you have set feeding schedules for them? I have a three month old and we currently feed him at set times but some times he will devour the bowl and sometimes he doesnt eat anything so I didnt know if maybe I should just have food down there all the time for him to decide when he is hungry or if I should stick with our feeding schedule (two or three times a day) Thank you so much for any advice!
