Listen, the idea with the automatic feeder is a real salvation for forgetful people like us! I would say, get something with a timer and portions, so that the dog eats on schedule, and not when you remember. Make sure that the volume is adjustable, from a couple of spoons to a bowl, and it is better for dry food, they rarely get along with wet food. Also get one with batteries, in case the power goes out. I used the
WOPET automatic pet feeder, first I drove it around the house so that the dogs got used to the sound, they sometimes buzz like a robots. Make sure to clean it too, make sure it is simple, remove the tray, rinse, and you're done. Set it up a couple of times a day, fill it with food, and that's it, the dog is full, and you are calm.
