I feed Jack once a day, at supper time "when I eat". Around 5-6 pm.
Being European, I used to eat my dinner between 8-9pm but, it was too late for Jack and he likes to eat when I eat. lol
I give him a 6oz. can of his Wellness chix and sweet potato,,, and leave out a cup of dry food all day and night.
I only use a cup because it can sit there at times and I don't want it going stale.
So a cup works good for my 7 pounder.
Always remember, our Yorkies like routine, so try to feed him or her the same time each day.
I keep to a schedule with Jack. This includes walking to.
It builds a more stable dog.
Inconsistency will only confuse and stress them out.
