帮忙看一下这篇作文有没有写的不对的地方~

two days ago,my little dog jesse had died.
jesse has been in my family for almost four months,she is a very cute and smart dog,she has a big head and eyes are pure.jesse is labrador retriever,so she is naughty and lively,she accompanied me to spend a pleasant time.
but now, she has gone.
jesse,i am so sorry.i shouldn't leave you alone at home that day,or else i can see that you will be as happy as usual in the cage after i going home and waiting for me to play with you ,and i think you will stay with me safely and happyily forever,above all i can watch you growing up every day......there are so many things i haven't done with you,Why do you suddenly leave me?
jesse,will you know my name if i see you in the heaven? will you still remember me?
jesse,my darlin.i miss you so much.

but now, she was gone.
you would still be as happy as usual in the cage后面还有一句一样

动物应该用it,而不是用she吧
