Bernedoodle Full Grown: Size & Weight

Q: How big do Bernedoodles get?

A full-grown Bernedoodle's adult weight depends on its variety: about 10–20 lb (Toy / Tiny), 20–45 lb (Mini), or 61–100 lb (Standard). Because the variant makes such a big difference, use the calculator above with your puppy's current age and weight for a tighter estimate.

Q: When do Bernedoodles stop growing?

Most Bernedoodles reach their full adult size around 12 months, in line with medium-size dogs. They do most of their growing in the first 6 months, then fill out more slowly.

A full-grown Bernedoodle weighs anywhere from 10 to 100 lb: it depends almost entirely on which of the three varieties you have.

How confident is this estimate? Based on an official breed standard or cross-checked veterinary/registry sources. As a designer/mixed breed, expect a wider band than for a purebred; two puppies from the same litter can finish at different sizes.

About this breed's data: Variant figures match PetMD (Toy <20 lb, Mini 20-45, Standard 61-100, up to 29 in). Daily Paws differs slightly: Standard up to 90 lb, Tiny 10-24 lb.
