If it gets sick or hurt really badly (broken bones) then it may be the time. However, if the dog seems to be okay, just let it live.
It could be part of a dream, or it could be simple incontinence--just as when elderly humans or babies urinate during sleep. They sell male and female diapers, which you can put on your dog overnight if need be, but really your dog needs to see a vet so you can start figuring out if the problem is physical or psychological and how to treat it best.
you can't
You can put the dog to sleep so that it will not infect other dogs.
Whenever HE/SHE is suffering.
you have to play the pipe
PTS = "Put to sleep"
Illegal? Yes it is. Unless the dog was legally put to sleep for health or safety reasons.
All dogs can pretty much sleep anywhere. At a pet store you can buy a "dog pillow" that you can put just about anywhere. Whether the dog will sleep on it or not is a different story. Most dogs will sleep on the bed with you.
Just put him/her in the bed with you,if the dog wants to get down just keep your door shut and he/she will learn to sleep with you. --------------------------------------------------------------------------- ^ Animal cruelty, give it a nice rimjob
Go to the vet or put him to sleep
sleep mostly
All individuals from the time they are born are dying to put it bluntly, but when getting older the elderly may have problems sleeping due to prescribed medications or, their brain cells are slowly dying off and can alter sleep patterns. However, some elderly people can be very active and can sleep their proper eight to ten hours. Elderly people can have bouts of insomnia and may take naps during the day because they don't have the energy they had when younger.
