No, it is a dog.

No.
<http://purl.org/stuff/pets#Basil> is a dog, and the same dog in fact,
in as much as pets:hasDogName is an inverse functional property.

<http://purl.org/stuff/pets> is an information resource.

Look it up and you may find some RDF which will tell you more about 
these things.
It is good practice to have an available document in RDF which gives 
lots of
useful information. But making that document available doesn't change 
the
nature of the dog, or what is or is not an Information Resource.
