I feed my Basset hound twice a day as he's on a special diet of white rice. Chicken breasts and cottage cheese. He seems to be fine with that.
Depends on the dog, but gor most two. Little puppies, 4-5 months and younger, should be fed 4 times a day. 6-9 months 3 times a day. Also dos with health issues might need to be fed smaller meals moes often. I had a dog that suffered from chronic pancreatitis and he was fed 3 times a day because it was easier on his digestive system.
