Dogs can be so funny sometimes! They are wonderful animals, they do not afraid to show their emotions, you can understand how they feel even from their beautiful eyes. You can understand when they need food, walk, sleep and games. They show you their love, sadness or happiness and I am sure you can easily understand when they feel guilty about something.
When you see your dog getting excited each time he sees you I guess is one of the most beautiful feelings. Your dog feels your absence and when he sees you he cannot control his happiness and his love so he runs straight at you!
