Things to notice:
- because begins a dependent clause, "because of his color". This clause is not segmented because it depends on the first clause, "Our puppy's name is Chocolate", to make sense.
- But begins an independent clause because a new subject is introduced. This clause can stand alone which is why it's segmented.
- Note that bound morphemes have not been marked.
puppy's --> puppy/z
there's --> there/'s
