Welsh Springer Spaniel Weight & Growth Chart
Complete weight guide with growth charts for male and female Welsh Springer Spaniels from puppy to adult.
The Welsh Springer Spaniel belongs to the Sporting group and originates from Wales. Adults typically weigh between 35 and 55 pounds, standing 17 to 19 inches at the shoulder. Life expectancy runs from 12 to 15 years, and the figures on this page describe that range rather than a single average, because the spread is what matters when you are deciding. Running costs settle around $154 a month once the dog is past puppyhood, before insurance and before anything unexpected. These numbers come from published breed standards and, where a standard is silent, from longevity and veterinary studies; they describe the breed as a population and not the dog in front of you. Line, upbringing, early socialisation and simple chance move an individual well away from the typical profile, and two dogs of the same breed often differ more than two dogs of different breeds. Nothing here is a diagnosis: for a specific animal, a veterinary surgeon who has examined it will always know more than a table.

When Does a Welsh Springer Spaniel Stop Growing?
Expect your Welsh Springer Spaniel to reach adult height of 17–19 inches by 12–15 months. Full body maturity, including muscle development toward the 35–55 lb target, may continue until 14–18 months.
Growth is influenced by genetics, nutrition quality, and spay/neuter timing. Generally healthy with moderate rates of common sporting breed conditions. Eye screening is particularly important for breeding stock..
Welsh Springer Spaniel Male vs Female Size Differences
Male and female Welsh Springer Spaniels differ noticeably in size, a pattern common in medium breeds. Males typically weigh 35–55 lbs, while females weigh 29–48 lbs. Both sexes stand 17–19 inches tall at the shoulder, though males tend to fall at the upper end of this range.
These size differences can influence practical ownership decisions. Larger males require more food, larger crate sizes, and stronger leash handling. Female Welsh Springer Spaniels at the lower weight range may be easier to manage physically for smaller handlers or families with children. Both sexes share the same temperament and health profile, so size preference should be a practical decision rather than a temperament-based one.
Is My Welsh Springer Spaniel Overweight?
Assessing your Welsh Springer Spaniel's body condition (healthy range: 35–55 lbs):
- Rib check: Run your hands along the ribcage, you should feel individual ribs under a slight fat layer
- Overhead view: A defined waist should be visible between ribs and hips
- Side profile: The abdomen should tuck upward behind the last rib
Overweight Welsh Springer Spaniels face higher risks of Hip Dysplasia, joint problems, and shortened lifespan. Even for a medium-sized breed, excess weight significantly impacts joint health and overall wellbeing. Work with your vet to adjust feeding and exercise if needed.
Welsh Springer Spaniel Weight Management Tips
Maintaining your Welsh Springer Spaniel at a healthy weight between 35 and 55 lbs is one of the most impactful things you can do for their long-term health. Studies consistently show that lean dogs live an average of 1.8–2.5 years longer than overweight dogs of the same breed.
Portion control: Use a measuring cup for every meal rather than estimating. Feed the amount recommended for your Welsh Springer Spaniel's ideal weight, not their current weight if they are overweight. Divide daily food into two meals for adults and three meals for puppies under six months.
Treat management: Treats should not exceed 10% of daily caloric intake. Use small, low-calorie training treats and consider using pieces of your dog's regular kibble as rewards during training sessions. Avoid table scraps entirely, as they add unpredictable calories and can introduce foods that are toxic to dogs.
Exercise alignment: With an exercise needs rating of 4/5, the Welsh Springer Spaniel requires vigorous daily activity. Insufficient exercise paired with full feeding portions guarantees weight gain. Ensure at least 60 minutes of activity daily, combining walks with active play sessions.
Regular weigh-ins: Weigh your Welsh Springer Spaniel monthly and track the trend. Gradual weight gain of even one to two pounds per month can lead to significant obesity over time. Your veterinarian can establish your dog's ideal weight during wellness visits and recommend caloric adjustments as needed.
Feeding Recommendation
Daily food for an adult Welsh Springer Spaniel: 0.5–1.1 cups of high-quality dry food in two meals, budgeting $57–88/month. Puppies growing toward 35–55 lbs need three to four daily feedings until around six months old. Generally healthy with moderate rates of common sporting breed conditions. Eye screening is particularly important for breeding stock., treats count toward daily calorie intake.
Welsh Springer Spaniel Weight by Age Table
The following table shows expected weight ranges for male and female Welsh Springer Spaniels at key developmental milestones. Individual dogs may fall slightly outside these ranges depending on genetics, nutrition, and activity level. Consult your veterinarian if your Welsh Springer Spaniel's weight deviates significantly from these benchmarks.
| Age | Male (lbs) | Female (lbs) |
|---|---|---|
| 3 months | 12.4–15.1 | 10.5–12.8 |
| 6 months | 27.3–33.2 | 23.2–28.3 |
| 9 months | 39.7–48.3 | 33.7–41.1 |
| 12 months | 49.6–60.4 | 42.1–51.4 |
Health Risks of Incorrect Weight in Welsh Springer Spaniels
Both underweight and overweight conditions pose serious health risks for the Welsh Springer Spaniel. Understanding these risks reinforces the importance of maintaining your dog within the 35–55 lb target range.
Overweight risks: Excess weight places additional strain on joints, increasing the risk and severity of conditions like Hip Dysplasia. Overweight Welsh Springer Spaniels also face higher rates of diabetes, heart disease, respiratory compromise, heat intolerance, and reduced lifespan. Even moderate excess weight, just 10–15% above ideal, shortens life expectancy and reduces quality of life.
Underweight risks: A Welsh Springer Spaniel consistently below 35 lbs may be experiencing inadequate nutrition, parasitic infection, dental problems that prevent eating, or underlying illness. Underweight dogs have weakened immune systems, poor coat quality, reduced energy, and slower healing. If your Welsh Springer Spaniel appears thin despite normal feeding, veterinary examination is essential to rule out medical causes.
