Families that decide to adopt a Bernedoodle have three sizes to choose from. A standard F1 Bernedoodle can be up to 90 pounds, but Bernedoodles can be bred with smaller Poodles to provide much smaller adult dogs. A micro or mini Bernedoodle is a medium-sized dog that can weigh between 20 and 45 pounds. A tiny Bernedoodle is even smaller with weight ranges between 10 and 24 pounds.
