Hello guys my name is Vi and i am desperately need many advices now, for my 1 year old beagle. actually this beagle got out from my neighbor house and turn out my neighbor and his family were going out for weeks for urgently reason, without knowing that the dog just escaped from the cage. So i decided to take care of her for uncertain times, before someone else kidnap, hurting or killing her. So my questions are :

1. This Beagle got so much energy, that i cant keep up her actions during our playful  time. What am i suppose to do with stamina like that? i am a woman anyway

2. i decide to put leash on her, because sometimes she's really disrespect me, by jumping around on me, biting my shoes, sandals, doormats, rag, etc.. but i kindda feel pity sometimes, so many times i unleashed her and guess what? She messed up everything around the house, and sometimes bite my pants.I cant believe her. how am i suppose to discipline her?]

3. how to make a beagle get along to another pet. especially when u have a duck?
