How do you know if a dog likes you?

Question

How do you know if a dog likes you?

Answer 1

If a dog likes you, he will wag his tail, some dogs will try to lick or jump on you.

If the dog is not trying to bite you, you are safe.

If he is just ignoring you...well...you get the point!

Answer 2

It wags its tail

But if a cat does so, run as fast as you can.
