When we just had Moose, we just free fed him. He mainly only ate when we were in the kitchen with him.
Then we got Mimi and she was a little food aggressive when we first got her. She also would eat all her food and then go and eat Moose's food too. He would let her
Mimi is 9.5 lbs and Moose is 14.5 lbs.
Both get 1/4 cup of kibble every morning, then at night (around 5:00) Mimi gets 1/2 cup of kibble and Moose gets 3/4 kibble.
So bottom line....Mimi get 3/4 cup per day and Moose 1 cup per day. We are very active. We walk 2 to 3 miles 4 to 5 times a week.
