Our dogs are four and six years old. We have been feeding them twice a day since each was one year old. Recently I came across a web page that argued quite well on the reasons why it is better to feed an adult dog only once a day. That text did not say (or I missed it) what would be a good time of day for feeding.
On this site I found an answer to another question (motionsickness in a car) where the answerer said "an adult dog only needs to be fed once a day and this is usually, best done in the evening."
Okay, we are now willing to change our routine and start feeding the dogs only once a day.
Why is evening better? The food we give our dogs is dry pellets, which in my imagination makes for easy digestion. Won't the dogs then have empty stomach by the next day and won't that make them restlessly looking for the next bowlful of food? My family is away from home during the day and I'd like our dogs to calmly rest that time. Wouldn't it be good to give them food in the morning before we leave for work and school?
