I’m currently working on feeding my dog to once daily, not because I’m not capable but because it will ease my stress. I’ve seen many big dogs who were fed once daily.
The problem now is I don’t know the best time whether every night or just morning.

She’s about 10 months older already

I used to feed my dogs in the evening when I had dogs.

if the dog weigh too much , and u aim to reduce size once a day is ok, for dog with normal weight twice is ideal while for puppy 3-4 times a day
