First thing you need to do is realize what a poor quality of life your dogs have.  Then you need to improve it.  Congratulations, you have taken the first step to a better future by asking help on this forum.

How about a doggie room instead of the crates?  Is there one room in your house that you can allow the dogs to be out and about?  Usually the kitchen works for this since most people have no carpet in the kitchen.  This makes clean-ups easier.  So install baby gates to keep them in the selected room when you are not there to supervise.  

If you have a yard outside the kitchen door then you want to put up a fence — you will find wire kennel fence and metal fence posts at any home improvement store (Home Depot, Lowes, Tractor Warehouse, etc).  You only need a small area for these small dogs.  Then install a doggie door in the kitchen door so the dogs can go in and out.

Once all that is in place you need to focus for ONE WEEK!  Just one week will probably solve most of your problems.  First teach them to go in and out the doggie door.  Tie up the flap and get on the opposite side of the door from the dogs.  Lure them out with great treats (hot dogs!  chicken!  YUM!), keep doing this until they are willing to walk in and out the opening.  Next untie the flap but lift it a little so they can see the treat and the other side.  Encourage them to paw and push at the flap to get out to you and the treats.  If they refuse to push, lift the flap a little higher and try again.  Once you are getting them to use the doggie door on their own they are almost house broken!

The way to get them house broken now that they have a way to let themselves outside is to encourage them to go outside every hour on the hour.  AND for 20 to 30 mins after they have a meal.  Go out with them and stand in the yard!  Celebrate when they pee and poop!  Give them 3 treats each time!  Let them know they are WONDERFUL pups for doing their business outside. Dogs do not like to soil where they live so their natural tendency will be for them to go outside once they understand they are living in the kitchen (or sunroom, or where ever you have given them space).  You just need to remind them to go out!  The focus of doing this for ONE WEEK is to get them in the habit of going out.  Their crates or beds should be in that room with them too.  But the only time they should be locked in the crates is when you are all out of the house.  This keeps them out of trouble and from being stolen out of the fenced yard.

Which ever room you pick for them should be one that humans visit often during the day (another good reason to use the kitchen) so that the dogs get to visit with you.  They will still feel part of the family but in a controlled environment.

Once they prove that they are not soiling the ‘dog room’ you can try giving them a little bit more freedom, say gating the dining room too.  Do this gradually and if there are any accidents in the second room go back to just allowing them one room.  They will slowly figure out that soiling a room puts it out of their reach. 

So, do some thinking about what could be the “dog room”.  Invest in a few baby/dog gates (make sure they are ones with a swinging gate for you to get in and out of the room – $40 to $60 depending on length at Targets), a doggie door (as low as $25 from Petco) and some fencing (50 feet for under $40, plus 9 posts for another $40).  A modest investment of time and money to be able to enjoy your dogs and give them a better life.

Do the right thing!
