Hi, i have a recurrent dream. I made it 3-4 times.

I'm walking with this big black dog, that in the dream is mine - i know this because i have, in the dream, a strong friendship with him. We come to a public bathroom, and enter. Then i take a bath in the sink - O_o - and when i finished i discover that the dog eated my shoes, but I'm not angry with him. Then some guys enter in the bathroom and scare me, but the dog chases them away.

What coult this dream mean?
Also, sorry for the bad english, but it isn't my native language.
