Pups always seem to slow down eating somewhere between 6-12 months. So it is normal. They aren't growing as quickly so they don't require as much food. I think it shocks most people when a pup that seems to enjoy eating suddenly doesn't want to eat. Happens to all of mine. Eat donkey poop outside? Yes? Dog food inside? No thank you.She decided the salmon food isn't good enough anymore so we are back to barely eating
My pup recently turned a year old and doesn't eat much now. They always will show increased interest in a new food, but that doesn't usually last. Best to pick one food and feed it. Otherwise they become very picky and you end up hand feeding them while they laugh at you.
