The Question
“Dear Dr. Paola,
I have a Mini Bernedoodle, Callie, who is currently seven months old and 29 Pounds — about how big will she get if her father was a 12-pound Poodle? ” – Jim
Quick Info about Callie
Hi Jim,
Thank you for sharing about Callie. At seven months and 29 pounds, she’s likely close to her adult size, though she may still fill out a bit more over the next few months. In mixed breeds like a Mini Bernedoodle crossed with a smaller Poodle, predicting final size isn’t exact, but we can make an educated estimate based on growth patterns and parent size.
Most small to medium breeds of dogs reach about 75 to 85 percent of their adult weight by six to seven months of age. Since Callie is already 29 pounds, it’s reasonable to expect she might finish somewhere between 32 to 38 pounds once fully mature, depending on her specific genetics. Think of her current phase as a teenager; her frame is mostly in place, but she may continue to add some muscle and body mass. By the time she’s around 12 to 14 months, you’ll have a clearer picture of her full size. I hope this helps!
