YOU SAID:
In my home there is a fat dog
INTO JAPANESE
私の家には太った犬がいます
BACK INTO ENGLISH
I have a fat dog in my house
INTO JAPANESE
家に太った犬がいます
BACK INTO ENGLISH
I have a fat dog at home
INTO JAPANESE
私は家に太った犬を飼っています
BACK INTO ENGLISH
I have a fat dog at home
That didn't even make that much sense in English.
