I have heard both good and bad... So I don't really know. Kinda surprised no one has chimed in on the subject yet. I have never used one so honestly (I feel stupid) I don't really know how they work, like how much they put out at a time and how often. I am assuming you can set it to the way you want. But.. That being said, I would assume, that if you have "gulpers" (pups that gulp there food down" it would probably be better to set the feeder on small amounts throughout the day so they don't gulp it down which can be dangerous and cause bloat. But also, I don't know your circumstances, are they left out all day while you are gone? Are you home all day, gone all day? How old are the puppies? Ya know, stuff like that I just don't know. I have read in puppy books and online that its not good to give a young pup free run of the house. One of my cane corso books (which is amazing by the way lol) says giving a young pup free run of the house is like bringing a young child to an amusement park and saying "here ya go have fun!" And just letting them run free... Lol... So my point is I guess, if they are young pups and on automatic feeders, how are they getting to it? Do they just have free run of house?
Anyway. Most of it comes down to personal preference. Are they running and eating food on their own? I have also read that it's good to be around them when they eat at a young age so that they don't get food aggressive. Like putting your hand in the food bowl while they are eating, let them eat some bites outta your hand... Lean over their backs (dominance) while they are eating... All stuff dominate pack members in a dog pack would do
so I guess I am saying that because if they are just running free and eating on their own alone it might cause a problem later down the road. But like I said I don't know your circumstances.
Anyway, hope that helped!
