I think whether a dog is really happy depends on whether the owner really owns a dog. People who really love dogs are very kind to dogs, so a happy dog always likes to be close to people he wants to be close to and feels like sharing happy moments. They often try to run to your side to get your attention, or lie on your feet, staring at you quietly, and even turn out their stomachs to seek touch.

These signals all reveal that they trust you and feel very relaxed and safe with you.

Playing with toys is another way for dogs to get attention, which means they are happy now.

A happy dog will shovel something to eat and destroy everything in the bowl. This is one of the most obvious signals to see if the dog is happy.

However, because dogs really eat too few patterns, the same dog food day after day may make them tired and no longer want to eat. At this time, you need to observe other signals at the same time to judge whether the dog is happy. If you find that dogs don't like to eat because they are unhappy, you might as well change something different from time to time to feed them.
