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.

Kerry Blue Terrier Health & Weight Management
The Kerry Blue Terrier is an Irish breed originally used for hunting vermin, herding sheep, and guarding farms. They are sturdy, medium-sized terriers with a distinctive soft, wavy blue coat. Kerry Blues are prone to hip dysplasia and a breed-specific neurological condition called cerebellar abiotrophy. Excess weight worsens joint stress and can mask early signs of mobility decline. They also have a higher-than-average risk of certain cancers, and maintaining lean body condition supports immune function during treatment.
Exercise: Kerry Blues need 45–60 minutes of daily exercise — brisk walks, play sessions, and off-leash exploration in safe areas. They are energetic terriers with strong prey drive and need both physical and mental challenges. They excel at agility, earthdog trials, and obedience. Without adequate stimulation, they become destructive and vocal.
Feeding tips: Feed measured meals twice daily using a quality adult dog formula. Kerry Blues are active dogs but can gain weight if overfed. Limit treats to 10% of daily calories. Their coat health benefits from omega-3 and omega-6 fatty acid supplementation. Avoid foods with artificial preservatives that may trigger skin sensitivities.
Keeping your Kerry Blue Terrier at a healthy 30–40 lbs (13–18 kg) supports their joints and overall longevity.
