My 2-year-old Hovawart currently has feeding times at 9 in the morning and again at 6 in the afternoon. In a month I will be starting evening classes so I have to change the feeding schedule to noon and 9 in the evening.
Is it better to gradually shift the feeding times towards the new schedule during the month, or just start with the new schedule abruptly? Is constant small change in the routine better or worse than one big change?
He's not the kind of dog that gets easily stressed over a change in routine, but I figure why not do it the "right" way anyway.
