Yeah I was thinking it would be easier as a actual backpack, but I don't like not seeing the pup or being able to talk to her (show her the world). Luckily she will be tiny (my Ozzy is only 20lbs full grown), so I'm hoping it'll be ok....My personal opinion i dont think the sling would be practical. I would see it slipping off shoulder if puppy wriggles. Also arm hitting into side when arms are moving. Would you consider a pet backpack for the actual back?
