Hello! I am new to this forum. We are first time English Mastiff owners. We love him so much! He is eight months old. We recently noticed him being more moody. Is this normal? Sometimes he just lays on the floor and whines at us. If we sit next to him he seems better but we can’t sit with him 24/7 as much as I’d love too. He has slowed down on eating as well. I’ve read that Mastiff’s are emotional so any feedback would be appreciated. He’s a healthy boy, he weighs just over 100 pounds right now.
