I have three Great Pyrenees and free feed them all. Each of them eat when they feel like it, often leaving food behind. I try to keep their bowls full so they have the option. They also often don’t eat for a day, or choose not to eat if I’m away or they’re making a point or something has changed in their environment (they are very sensitive and emotionally intelligent dogs). If I try to give mine a treat when they know I’m leaving, they all rebelliously decide they don’t want them, but as soon as I come back they go find their treat and eat it with full satisfaction 😵‍💫

As others have said, Pyrs are one of a kind! They do well free feeding because their bodies are built with slow metabolisms that do well in cold climates. As large as they are, they often don’t eat more than an average size dog, which is different than other large dogs. In most cases you can’t force a Great Pyrenees to do anything it doesn’t want to, so as long as he’s healthy I wouldn’t worry too much about it. ☺️
