Dog Health Questions: So my older bi-polar sister just got a dog?

Anyway, she is my adopted sister and she is about 11 years older (I am 13 she is 24) and she has 3 kids and a boy friend. She lives in an apartment about a half block from my house. She has a reputation for getting animals then suddenly not wanting them (She did this with MY cat). And she saw this lady that was giving away this free puppy. Well, the puppy is a chihuahua/poodle mix (So she says. I believe she has some shih tzu in her as well) and about 8 to 9 weeks old. She is the cutest little girl but I am so afraid for her health while living with my sister. I decided that I would happily take the poor pooch for a walk every once in a while so that she will learn some things (I researched a lot about dog training and trained my great dane that way) and to get her out away from that nasty environment. Once school starts(The 6th of September), I will be able to take her for a walk every day (I am not allowed to take ours for a walk due to the fact that he gets too nervous around people) But I want some advice. This is going to be hard and I really want That dog to turn out okay. Here is kind of what she looks like:

Recommended Answer:
I think it's great your looking out for the dog. My advice would be to offer to walk the dog everyday and also offer to dog sit for her. You can also teach the dog basic obedience.

• i don't understand what bipolar as to do with dog ownership ... a person who is bipolar is not equal to low IQ ... if your sister is a crappy pet owner, then say that, but it has nothing to do with her mental illness ... bipolar is a mood disorder and people with bipolar can live normal lives including having families AND pets ... and nothing you described is a "nasty environment" it is just a woman with mental illness living her life with her family ... if she got tired of your cat, so what ... she is clearly a dog person ... i feel bad for your sister she has such a judgmental and a titch mean sister ... and with your extra details, you can't even train and socialize your own dog, so what makes you better for this puppy ???
