ok this sunday i just got a puppy (my first). she is 3 and 1/2 months old. well i can never get it to sleep by herself. it has to be somewhere where she can see me. if shes ever alone then she whines and cries. i tried leaving her in a room by herself one night and she was crying extremely loud. i tried to ignore it and fell asleep. around very early morning i woke up and heard her still barking and crying. she didnt sleep all night! and when im gone to school (weekdays 6 am to 3 pm) she cries at home all night. she hates her crate. its the worst thing to her. when i put her in there she cries terribly. ive left toys and everything for her. i tried all the tricks i can think of: t-shirt, ticking clock, etc. i just let her roam the house, because i dont have a room for her to stay in, except the garage. should i leave it in the garage for many hours during the day? i need alot of help. i cant sleep all night. i have responsibility over her. i sleep in all of my classes because i dont get enough sleep at home, due to comforting it at night. while i am in class i think about her all day. im wondering, is she crying? is she using the bathroom on the carpet? (its not housebroken yet, i cant seem to potty train her )when she cries, i cry. well i have another problem with her. she constantly bites my hands and arms. it starts as playful nibbles but when i try to tug my hand away it bites harder and starts growling. then now it shakes my hand and chews it like a rope. you know that thing when dogs got a hold of something in its mouth and then it violently shakes its head left to right? well thats what roxy was doing to my hand. it hurts. i have big scars all around my hand and arm now. what can i do? how can i train it to be obedient and stop biting? please help.
