As we human beings need a schedule for healthy living, same is the case with your furry friends. If their bowls are full all the time then it may make them lazy and fatty and hence schedule is better. Actually I got my dogs groomed from Boom Towne and they had suggested me to feed the dogs at some intervals and from that time I, myself have a schedule for my dogs and give them food and water at some intervals and I found that my dogs are more active than before.
