These little guys and gals are smart. I have been training dogs my whole life, and I tend to believe my current little guy is probably the smartest I have trained. I started him off in training the day he arrived in my home (at 1 year old) for house and door training, then the rest one week after he arrived so his neutering could heal. He was completely untrained. No house training, and no commands. He tore up stuff and chewed a few holes in my carpet. He is now a completely different, confident and very happy little guy!! In ten weeks he had already learned:
1. Sit
2. Lay down
3. Speak
4. High five (just for fun of course)
5. Sit and wait for specific release command to go outside and come in (ignoring all other words until he hears the word "okay").
6. Sit and wait for specific release command to go to his food (ignoring all other words until he hears the word "okay").
7. Stay for several minutes with me in sight or out of sight.
8. "Leave it" including when food is dropped near him.
9. House trained
10. Roll over
11. Controlled load and unload from car
12. Leash trained to sit when we stop and stay until command to get up
It will take you longer since your dog is used to you letting it do whatever she wants. Once she realizes the tides have turned and you are
going to be 100% patiently consistent, she will begin to learn rapidly. Your dog and everyone your dog is around will so much happier if you train her. Right now she is a very confused dog because she does not know how to behave better, but she knows their is tension in the house surrounding her, and she gets in trouble without understanding.
Here is a free website that offers both training ideas, and tips for problems in training:
Introduction | Mind to Mind
Whatever else you do, train the dog. Many dogs who are impossible to live with (untrained) end up euthanized.
