Can we draw the following hypothesis from the context?

Context:

Stains<br>I tried not to do anything to mess up the new carpet. I was very careful while I cleaned the house. Just as I turned from picking up a can, my dog ran into me. The can flew out of my hand and hit the carpet. There was now a huge soda stain that I couldn't get out.

Hypothesis: The dog was a pitbull
It's impossible to say
