I take my dog most places with me. I don't 'enforce' him on anyone who doesn't want him though so if people say no, I just don't go or do as others suggest; meet in dog friendly places.
I would add my dog is very well behaved, doesn't shed hair and doesn't pee in the house 
No reason anybody should put up with a dog but also no reason a person with a dog should leave it behind if its what they want to do.
I guess it depends on the dog and how much you want your friend to visit your house then eh?
My dog doesn't normally sleep in the bedroom but when we go on holiday, to dog friendly hotels, he does! I can't see a problem with dogs in bedrooms so long as they are flea ridden lol. After all, the way I look at it is....kids make ten times more mess!
