Sydney has two kinds of bowls .
I use a metal bowl for his wet food . Is much easier to clean and scrub !!
He has a plastic bowl for dry food and one for water . These are both of the upside-down-bottle-in-bowl . With these you do not have to refill all the time ; and Sydney will never over-eate when it is about dry food !!!!!
Wet food makes him go nuts !!! He LOVES that !!!!So , only one portion a day !!
