"Yo tengo un perro."
Translation:I have a dog.
I'm not really sure how I wrote it correctly and it marked me wrong can be misinterpreted. At the end of the day, I have a screen shot of it written correctly and put here for app developers not someone with nothing better to do then anonymously write inaccurate comments.
According to the notes that came up when I tapped "tengo", this sentence could also translate as "I am a dog". What then is the meaning of "soy"?
