麻烦英语高手帮我修改一下这句话的语法,可以的话意思不变的情况下修改这句话的结构,
However,the date I been there was mid-February and then I found out the earliest dog living there was came in by mid-January.I guess it might not be a long time for dogs to stay.我去的日子大约是2月中旬,我发现再那里呆的时间最长的狗狗也只有一月中旬,所以我猜想可能狗狗并不能在这里待很长的时间
意思是说，我去的时候是2月中旬，在那里呆的时间最长的狗狗被送来的时间是一月中旬

Answer 1

I went there in about mid-February and found out that the dog that stayed there the longest was only one month.So I thought the dog(s) could not stay there for a long time.
