Sometimes its impossible to take a dog with you, consequently you must, for the dogs sake, condition her to being happy on her own. You will need to go to the hairdressers, the dentist and the doctors. I adore dogs and my dogs have always slept in my bedroom after they are potty trained and after they are conditioned to being on their own.
There are thousands of unkind people who buy a puppy and leave it alone in misery when they go to work. I am delighted to read a post from such a dedicated owner who cares and takes her dog to work. BUT BUT BUT. There are thousands of dogs who suffer from Separation Anxiety, this is a dreadful affliction and a dog can suffer from this for the rest of it's life. . Dogs feel that their world is coming to an end when they cannot see their mum, consequently you must resolve this.NOW.
Ignore the hard hearted answerer's who tell you to leave your dog to whine, these answers will be from people who left their puppy to cry all night when it was separated from its mother and siblings and some of these dogs will always feel insecure.
Please do the following which I will paste and then when your dog is content to sleep on her own, try for her sake to harden your heart in the knowledge that you have resolved her separation anxiety and let her sleep on her own. The following refers to a male dog, however I have always preferred b1tches.
After he has been fed and CARRIED out to the garden for his pees and poos, let him wander around the garden, then put him in a room on his own with a comfortable bed. Close the door and then immediately go back into the room and IGNORE HIM. Spend a minute or two cleaning your work tops if he is in the kitchen, or pretending to be occupied with something else. Walk out again and close the door and walk back in again immediately. Keep doing this over and over again. Eventually you can leave a short gap before you go back into the kitchen, when you know that he is asleep you can stop doing this.
You must listen for him waking up and you MUST GET TO HIM BEFORE HE CRIES. Pick him up and CARRY him into the garden.
Play with him and let him explore the garden. If it's time for another meal, give him this and take him out again, because he will want another pee. (Always praise your dog profusely when he pees or poos outside). Then put him into his bed, close the door to his room and start doing the door thing over and over again.
This is time consuming, however it works. By the end of day one he will have been put to bed several times and he will think that you are just on the other side of the door. Continue doing this for a couple of days and he will grow up without Separation Anxiety and he will stop crying at night. My dogs have never had Separation Anxiety; I think that they think that I never leave the house. Nevertheless I sleep downstairs for the first two nights.
I have given this advice to several people and it has worked very quickly, I know this because I have had emails from them.
Eventually try to leave your dog to sleep downstairs on her own. Loving a dog is not having them with you for twenty four hours a day. Love is training them to be confident and happy when you are not there.
