When do Cockapoos stop growing?

As a small breed, Cockapoos usually reach their adult weight at around 10-12 months, and are typically about half their adult weight by around 4 months. They may keep filling out (gaining muscle and chest depth) for a few months after their height stops increasing.

Feeding a growing Cockapoo

  • Feed a complete puppy food.
  • Split food into 3-4 meals a day until about 6 months, then 2 meals.
  • Keep your puppy lean. You should be able to feel the ribs easily. Use the dog food calculator (puppy setting) as a starting point.
  • Weigh your puppy every 1-2 weeks and compare with the chart above.

Is my Cockapoo puppy overweight or underweight?

A puppy slightly outside the chart range is usually fine if it is active, eating well and has a good body shape. Talk to your vet if your puppy is far outside the range, stops gaining weight, or looks pot-bellied or bony. Parents' size is a strong clue: puppies from smaller parents often finish at the lower end.
