Thanks for your answers, they do help.
I agree with you, Golden retrievers are super loyal, I grew up with one and his name was Duke, he brought us to the school bus everyday and back.
Dogs in dreams when they don't mean anything specific to a person represent relationships, obligations, responsibilities, and like we talked about-loyalties.
Beds are places of personal space, intimacies, so the dog is in your bed so your dream is about you and your personal space.
He is even under the covers, so this could show that there is something hidden or covered up.
Is there someone who you are in relationship with that is very submissive and does not have any boundaries?
Someone who you feel intrudes on your personal space and demands to much of your attention?
This may not be a person, it could be a job, a attitude, a passion of some sort, anything that fits along those lines in your real life.
What is sticking with you no matter what? This could even be a bad habit that you are trying to rise above.
You as the dreamer will know best on how this fits.
Please, if you have any questions or comments please reply back to me I am happy to help.
