Mechanical Angel -- I'm going to play the middle ground here. First I want to welcome you. This IS a good place to get questions answered. However, one of the very *first* things you need to learn/know how to do is how to set up a situation to get what you want ... not what will make you frustrated!!
Dog owners/lovers/trainers LIVE by that. That's what got everyone so frustrated at first because you asked the most open-ended, completely without parameters question you could have asked us.
So -- let's back up just a bit and stack the deck in your favor, ok? You still honestly haven't answered any of the questions directed at you, and honestly ... in order for us to truly *help* you, we need to know things. Because it's frustrating for us to start at a beginning that is *not* where you are. It causes us to make false assumptions about what you do and don't know ... and that's only going to cause trauma.
So ... Let's start with the basics, ok?
1. You said you're getting this pup in six weeks. That number is a magic hot button that you may not understand yet. (Janet's question wanting to be sure the pup wouldn't be six weeks old.).
So, please tell us your own background.
a. How old will the pup be when you get it?
b. Is it coming from a breeder you know well? What sort of genetic testing has the breeder done -- or are you already aware of the serious genetic problems that can face chi owners?
c. Will you get any guidance from your breeder? Food help? how housebroken will the puppy be?
d. There must be some decision that surrounds that date. Did you look for a puppy to coincide with getting out of school? A pre-planned vacation? The litter was just born and that's the deadline for the breeder to want to be rid of the dog?
All those scenarios put a HUGE slant on how we'd phrase advice for you. That's why we need to know. We're not being nosey. It's really that varied.
2. Tell us about YOU. Yep, that's important. Are you single and alone? Apartment or home? Home all day or will the pup be alone? Country or city?
Do you have a fenced yard? Or do you plan to walk this dog every time it has to potty? Some other choice?
Have you ever had a dog before at all? do you plan to show this dog or is it simply a pet/companion?
3. What made you choose a chi? And which of the chi varieties did you choose? Coat? What attracted you to the breed?
4. What boundaries do you have to function within? (This goes along with the question above about vacation or dates.) Housetraining is a multi-layered task that takes MONTHS to accomplish. In fact, to be completely honest, it isn't "reliable" for pretty much the first 9 months. It's 7-8 months before a pup physically develops enough to tolerate being crated for a "work" day (even if it's kept to a minimal 8 or 8 1/2 hours away from home).
If you are mechanical, my guess is you need some structure and we'd love to help you -- but let's try to do this the easy way.
It's just a whole lot easier for you and a better use of our time to give you GOOD information, rather than drawing erroneous conclusions that may upset everyone. We truly aren't trying to be nosey -- and if you are concerned that some of your answers may be 'wrong' or if it is off-putting to relate any such information on a public forum, feel free to email me or any of us who have that option listed.
Welcome, and enjoy the journey with your pup.
