We brought home our little poodle pup on Saturday. She's doing brilliantly with the house training - goes almost as soon as we take her outside and only about 4 accidents over the last 3 days including nights and our own stupidity! 
My question is - she doesn't seem to do very big wees. She's done one big puddle on the floor but the others have been very small. Similarly - outside she will do one wee and then a few minutes later another. Sometimes even another after another few minutes! She doesn't do that inside though so definitely a choice she's making and not involuntary iyswim. Is that normal? Just worried she might have a puppy uti or something!
She hates going out in the rain (which it has done solidly here for 2 days!) and the cold so if I make her go out she runs to the grass does a quick wee and then runs back to the door ASAP! I sympathise with her - but worrying she's not properly emptying her bladder. 
Next thing: she keeps nipping ds2 who is nearly 3. She's very stimulated by him walking and wants to chase and then bite (quite hard) and pull at his clothes.
Ds has been very good - he stops still ignores her and will try to distract her or I do. But it's getting a bit much - today I put her on the lead when we were playing in th garden for a bit so when she ran at him I could pull her off before hand. Is that the right solution or can I scold her when she nips? Ignoring doesn't seem to bother her at all and whilst it is normal it's very very targeted at ds2 which i think is beginning to annoy him. Help a newbie please
