The dog:

His thoughts:

1. Why is this lady photographing me?

2. Am I a dog?

3. Why am I dressed as a skeleton?

4. When am I going to be fed?

5. Why am I standing next to a guy dressed an an octopus?

6. Why are all of these people staring at me?

7. Am I going to end up on a blog the day after tomorrow?

Well, dog, with the last thought, you are correct!!!
