Having dogs in your bed is unhygienic full stop. That's not just a Muslim view, but a view regardless of religion/culture. This is from one vetenary website:
Besides blurring the lines between pet and owner, when you allow your dog to sleep in the bed with you, you are also allowing your dog to bring a host of dirt, bacteria and other substances from outdoors right into bed with you. Most professionals would agree that this practice is very unhygienic.
As for the Islamic view, then that is that keeping a dog as a pet inside the house is not allowed (and this is regardless of its colour).
Here are a couple of relevant hadeeths:
Narrated Ibn `Umar: The Prophet (peace be upon him) said, "Whoever keeps a (pet) dog which is neither a watch dog nor a hunting dog, will get a daily deduction of two Qirat from his good deeds."
(Saheeh al-Bukhari Vol. 7, Book 67, Hadith 389)
It was narrated from Abu Talhah that:
The Prophet (peace be upon him) said: "The angels do not enter a house in which there is a dog or an image (of an animate being)."
(Sunan an-Nasai Vol. 6, Book 2, Hadith 5349)
