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.

Welsh Springer Spaniel Health & Weight Management
Welsh Springer Spaniels are compact, athletic gun dogs from Wales, distinct from the more common English Springer with their rich chestnut-and-white coat and smaller, more streamlined build. Weighing 35–45 lbs, they were bred to flush and retrieve game in the dense Welsh countryside. They are prone to hip dysplasia, elbow dysplasia, glaucoma, and otitis externa. Their compact, muscular build means they carry weight efficiently, but excess fat still worsens joint deterioration and adds strain to hips and elbows already predisposed to dysplasia.
Exercise: Welsh Springer Spaniels need 60+ minutes of vigorous daily exercise. They are tireless field dogs that love swimming, retrieving, hiking, and scent work. A Welsh Springer without adequate exercise becomes restless, vocal, and destructive. They are born to work — combine physical activity with training, field work, or hunt tests to keep them satisfied. Always check ears after water activity to prevent infections.
Feeding tips: Feed two measured meals daily using a quality active-breed or sporting-dog formula. Working Welsh Springers need higher caloric intake during hunting season — adjust portions seasonally. Off-season, reduce calories to match lower activity. Avoid free-feeding and limit treats. Their pendulous ears require good nutrition to support immune function and reduce infection frequency.
Keeping your Welsh Springer Spaniel at a healthy 35–45 lbs (16–20 kg) supports joint longevity and field performance.
