Sometimes yes, sometimes no. My wife and I love how snuggly our dog is, but she's a big of a bed hog! (The dog, not the- Well, ok, the wife, too.) Ripley (our pit bull mix) has to get right between both of us, and will not accept no for an answer.
Thankfully, she does sleep through the night, and does bother us when we let her sleep with us.
Unthankfully, she makes the bed smell. In fact, pretty much the whole room. I don't know what it is about her, but she'll get that dog smell, and strong, too, a day after we bathe her. But the snuggling is sometimes worth it.
