Dogs are very loving animals, of all the pets they have been labelled "man's best friend" because they are loyal and affectionate. Dogs make it fairly obvious when they love you but there are also some common signs of affection they display:
Like with humans, when you love someone, they are the person you want to be around. This behaviour is typical of dogs. Dogs follow you around in order to stay with you and be by your side. It can also be seen as a sign of protection by staying with you.
When puppies want to be fed they lick their mothers. When they are older they will lick other dogs as a sign of respect. This acknowledges the status of an older dog within their pack. Dogs can also lick you when they are anxious or stressed, but the most likely case is in a relaxed form when they are just licking you as a sign or affection and respect.
When a dog wags its tail slowly it is most likely to suggest the dog is unsure and is accessing the environment around it. Large, faster wags of the tail indicate happiness and excitement and can be seen as a sign of affection if they wag their tail fast when they see you.
When a dog rolls over it is a sign of trust and relaxation. Rolling over is one of the most common signs of affection (usually with the invitation of a tummy rub!)
In many occasions when a dog is happy and excited to see you, they will jump up and get your attention. Jumping can however also be seen as an attempt at dominance and if you are unhappy with your dog jumping up you must ensure you teach it not to from a young age.
Resting their head on your lap is a sign of love, affection and trust. It is also an invitation for a nice head rub and scratch behind the ears!
Rubbing Up Against You
This may seem like a characteristic of a cat but actually dogs do it too to show affection and get your attention.
Please remember that although the above characteristics are signs of affection from dogs, every animal is different and some can also suggest an attempt to assert dominance. You and your dog will however develop an understanding of each other so that you can show each other mutual affection.
