hour 1: in the house, go into a room, close the door – dog outside the room. Count to 10 open the door, walk to the next room (do not interact with the dog). Repeat in every room in the house that can be closed off with a door and every closet in the house until you can be in a room/closet for 5 minutes.
hour 2: Do exactly the same as hour one except when you come out of the room, provided the dog is not going nuts and is calm, play WITH the dog (push a war, smack it, tug, something interactive IT MUST INVOLVE PLAYING WITH YOU). You should be able to get to 10 minutes separated from the dog in a room or closet by the end of this hour. The play session should not last more then 1 minute. You can do more then one play session each time with a break of 30 seconds between 1 minute sessions.
hour 3: repeat hour 2, this time with food instead of play. Food should be accompanied by the HUMAN getting really excited about giving the food to the door. Get to 15 minutes. Obviously that means only 4 or 5 rooms will be used in an hour.
Take a break until evening, do not feed the dog dinner.
Hour 5: Write down every routine you go through when you are about to leave the house. It doesn’t matter whether the routine is for going to get the mail, or going shopping, or going to work. Humans are creatures of habit and routine and if you think about it, you can write down every step you take in each type of routine. Put each step in those routines EACH on a 3X5 card and shuffle them. Then grab 5 cards, do the actions in those 5 cards (even if it means putting on your shoes and then taking a shower). At the end of each 5 card routine, go outside rotating doors each time, and continue your counts until you can get to 10 minutes outside with no reaction from the dog.
Hour 6: Do hour 2’s actions of play, but instead of room and closets, go outside. Try and get to 15 minutes.
Hours 4,5,6 Continue what you were doing in the morning, get to 30 minutes separation time and 2 minutes between 1 minute play sessions.
This is the day for the long separation times. When you get up, shuffle your cards and pick out 10 to do, then leave the house for 30 minutes, actually driving away – you can run some errands if you wish so you come home with a bag or two of stuff. When you get home, walk in, ignore the dog no matter what he is doing. Wait until he is calm and then have a 10 minute play sessions (30 seconds on, 30 seconds off).
Wait two hours and repeat with a new set of 10 cards. Leave for 45 minutes, make sure to come back with dog goodies. Again wait until the dog is calm if necessary and have a 15 minute play session.
Wait 3 hours, do a normal leaving routine for going to work and then leave for 90 minutes. Everything should be fine by this time. The dog should have the concept that you will always come back and that if he is calm you will play with him for a long time. 15 minutes is a long time for a dog.
Notice that you don’t need to take your dog for a walk during these three days. Your dog will be really tired from the mental exercise and the play sessions.
The intention with these three games is to put so much value into playing WITH you, that anything you have is also valuable. The toy you are squeaking becomes valuable to the dog and he wants it Then you can start with tug, drop, run (wait til your dog bites the toy, drop it and run – he should run after you with the toy in his mouth).
Make this whole routine fun for both you and the dog. You can enthusiastically charge out of closets and rooms to start the play sessions or throwing a handful of treats (or his dinner). Really get into the card shuffle game and realize how silly humans are with their routines and habits and laugh at yourself. Your emotions and energy level will affect how well your dog does with this.
