I've fed Rocco 3x per day since he was 8 weeks old (6am, 12noon, 6pm), and he seems to do fine with this. He also gets a snack or two at night (maybe a biscuit or some training treats) and I have water down for him at all times (since he's not even 6 months old). If 4x per day is working for your pup, that's fine but I'd maybe spread out the feedings more (how early is she up/when to bed?). And it is a good idea you're doing to remove the food after 30min...this is good for hygiene as well as potty training.
By the way, I'll be visiting your beautiful country next week as well as in July
...you're very fortunate to live in such a beautiful climate. And Welcome to YT!!!
