so we got a puppy about a month and half ago and he was advertised as a F1B mini Goldendoodle. Meaning his mom is a Goldendoodle and dad is a poodle however we are having some doubts he is not getting that big . At 14 weeks he weighs 5.31 pounds . How big was y'all mini around 14 weeks any thoughts ? Could he maybe be something else ?!
