Yeah, I know Pom's aren't good for outside, but atm we need to keep her outside cos AS SOON as she comes in she pees and poos. So we're thinking of keeping her outside until she's fully house broken then slowly putting her back in the house. We used to keep her inside but it didn't work. And I do believe that my doggie's house is very cosy since there are pillows, cushions and fat jumpers in her little box, I really don't think she'll get cold since there are like 5 big fat blankets to cover the wind from coming into her house thingy, (we also make her wear a jumper). If you still don't think that's warm enough please let me know. And if anyone has any spare information about training puppuies to walk on leashes, and stop barking at people and other dogs please let me know....
You cannot housebreak a dog unless the dog is actually IN THE HOUSE.
Do you have a crate for her yet? I know it was advised in one of your very first threads. A crate will help you a lot when it comes to housebreaking your puppy. You also need a lot of patience and good timing.
As for the leash, does she wear her collar around the house (or apparently yard)? Start her off by having her wear her collar almost all the time. Once she's used to the collar you can add a super small lightweight leash and if she pulls you stop walking. As soon as she stops pulling you say "good girl!!" and give her treats and affection. This can make a normally 5 minute walk take an hour, but again, when training dogs you need patience. That's just step one. Work on that for now.
As far as the people and other dogs: how much interaction does she have with people and other dogs? With puppies you need to socialize the heck out of them. Take her downtown, take her to TRAINING CLASS, take her to puppy playgroups.
I don't mean to get down on you, but so far everything you're doing with this puppy is wrong. You absolutely need to save your pennies and get into a puppy class ASAP or else your poor puppy will always eliminate in the house, always bark at people and dogs, and life with your Pom will be miserable.
