Can we draw the following hypothesis from the context? 

Context:

A New Friend<br>John left his house to go grocery shopping. Before he made it, he saw a stray dog on the sidewalk. He stopped to check for a collar, but there was none. He took the dog home, and named him Frank. Frank and John are now best friends.

Hypothesis: John and Frank may be best friends, but only one of them is a human.
