1. Maybe it's a missing dog.

2. Maybe it's a stray dog.
3. Maybe it's a homeless dog.
4. Maybe it's a ownerless dog.

Are they the same in meaning? #1 seems to be the same as #2. Am I right? What about the others......Take care.

1 means the dog has a home, but is missing. His owners are probably frantically looking for him.

2-4 mean about the same thing, but be sure to put "an" before "ownerless."
