All dogs can be housetrained, some may take more time and some may be harder to train, but all dogs can be successfully trained. The first thing you need to do is figure out how many times a day your dogs goes to the bathroom, of those times, how many times does she pee and how many times does she poo? By figuring this out, you will be able to determine a pattern or schedule for your dog and when to take her to go potty and how many times she needs to go. If you can figure this out, it will make training so much easier.
For example, my trixie goes to potty four times a day. All four times she pees and two of those times she poops. She pees and poops in the morning and at night, the other two times she just pees. From this I have learned that she needs let out every 6 hours.
Alright, first thing in the morning let your pup out of her crate and take her to the place you want her to go (pee pad or outside) and as soon as you place her down on the spot, tell her "go potty". If you say this everytime after you put her in the spot, you will soon recognize this command and when you say this she will know what she is suppose to do. If she does go potty, give her lots and lots of praise and a special treat that she will only get when she goes potty.
Do not let her wander off of the pad, keep her on it until she goes. If she does not go (give her 5 minutes), put her back in her crate. In 5 to 10 minutes, let her out again and give her a chance to go. Keep repeating this until she goes.
As an additional reward to seal the deal, if she goes, give her play time for a while. She will soon learn that in order to get out of the crate for play time she must go potty first.
All of my dogs know that in order for them to get out to play the must go to the bathroom first.
When she is out, make sure you either are giving her 200 percent of your attention, or tie her to your waist. This way if she is looking to go to the bathroom you will be able to catch her before she does and take her to the right spot.
Note: everytime before you go to put her in her spot for her to go potty, ask her in a pleasant high pitch voice "do you go to go potty". She will learn to recognize this phrase and when you ask her she will be able to give you some sign that she has to go. So all you will have to do is ask her and she will be able to tell you when she has to go. This part takes the most time for them to understand. Watch for her signs that she has to go.
My one dog, when asked do you go to go out will run to the door and then run back to me and will repeat this until I get to the door. If she does not have to go then she does not do this.
My other dog when asked, will back up, bark twice and whine. She will repeat this until I get up to let her out. When she does not have to go, she acts normal.
The key to training any dog is consistency and patience. Some dogs it will take longer and will be harder to train, but they all get be trained.
As time goes on and your dog starts making improvements, then you can increase her time out of her crate and give her more priveledges. Until then, she will have to spend more time in the crate. Eventually, you will be able to give her the run of the house without her having any accidents.
I have had over a dozen dogs and I have successfully housetrained them all by using this method, and I am sure you will too!! If you have any questions feel free to ask. Good Luck with the training, and let us know how it goes!
