What breed are you?

Today I was helping ma deliver letters for work and we were followed by a dog I'd never seen before... 

Ma thought he looked French... Ma's boss said it was a hyena! 

He didn't have much fur... So I hope his pawrents buy him a jumper for winter! 

He was very streetwise and walked Ma back to work... & then walked himself home! 

Do any of my friends know what breed my new friend is?
