I have a problem my husband use to walk my yorkie from 7am to 7:30am then I would feed him about 8:30 and go to the 9 am gym class but now he doesn’t walk him until 8 am to 8:30am and I’ve been feeding him at 9 but I can’t go to the gym.Is it better to walk or eat first and how long do u wait after if u walk first?
