How the puppy weight predictor works
This predictor uses growth milestone data from Salt et al. (2017), published in Veterinary Record, which tracked the weight development of dogs across five size categories from birth to adulthood. By comparing your puppy's current weight against the expected growth percentage for their age and size category, we estimate their adult weight range.
Factors that affect adult weight
Genetics play the largest role, but nutrition, neutering status, and overall health also influence growth rate. Puppies fed excessive calories during rapid growth phases may exceed their genetic weight potential, while underfed puppies may not reach it. Large and giant breeds grow more slowly than toy and small breeds, reaching full size at 18–24 months rather than 10–12 months.

English Cocker Spaniel Health & Weight Management
The English Cocker Spaniel is a compact, cheerful flushing spaniel originally bred to flush game from dense cover in the English countryside. Slightly larger than their American cousin at 26–35 lbs, they are sturdy and energetic with a silky, feathered coat. English Cockers are prone to ear infections due to their long, pendulous ears that trap moisture, and to hip dysplasia. Excess weight worsens joint stress and compounds ear problems in this active breed. They are also susceptible to familial nephropathy, and maintaining a lean body condition supports overall organ health.
Exercise: English Cockers need 45–60 minutes of daily exercise — brisk walks, field work, retrieving, and play. They are enthusiastic workers with surprisingly high endurance for their size. A Cocker without enough exercise becomes hyperactive and vocal. They love swimming and make excellent companions for hiking and agility at a moderate level.
Feeding tips: Feed two measured meals daily using a medium-breed or active-dog formula. Cockers are food-driven and will happily overeat. Check and clean ears after every meal — their long ears dangle into food and water bowls. Use a narrow, deep bowl to minimize ear dunking. Limit treats and use portions of daily kibble for training rewards.
Keeping your English Cocker Spaniel at a healthy 26–35 lbs (12–16 kg) supports joint and ear health. Use PawScale's calorie calculator for English Cocker Spaniels to set exact daily limits, check body condition with our BCS assessment tool, and build a balanced meal plan with the feeding guide.
