Hi
re. 1st question, as soon as her teeth make contact use either a deterrent (ah!ah!) or introduce a command word such as "gently" :) Be persistent and consistent - she sounds as though she's getting over excited and so if things are going that way stop the game until she settles.
re 2nd question. Dogs which have repeated soft motions often do so because of diet - it can be too much food (rather than too little) or something which is slightly disagreeing with them. I'd cut out the rawhide - personally I think they're dangerous as they can become lodged in the GI system and cause an obstruction. If she gets these as a recreational reward rather than as part of her daily food quota, then substitute with a large recreational knuckle bone which will keep her busy and help keep her teeth clean, gums healthy :)
If the above stops loose stools and you think she needs more to eat, then increase the biscuit part of her diet or give her a late night snack to stave off hunger pangs.
There are lots of alternative food choices available but I see no point in suggesting a change in diet if you are otherwise happy with her overall condition but would add that firmer motions should prevent the anal gland problem too.
HTH, Teri
