When Does a Portuguese Water Dog Stop Growing?

The Portuguese Water Dog stops growing in height (target: 17–23 inches) around 12–15 months of age, but may continue adding weight toward 60 lbs for a few more months. Males weigh 42-60 pounds, females 35-50 pounds; the breed should be muscular and athletic, built for endurance swimming and agility..

Their curly coat may also undergo changes during this period, reaching its adult texture by maturity.

Portuguese Water Dog Male vs Female Size Differences

Male and female Portuguese Water Dogs differ noticeably in size, a pattern common in medium breeds. Males typically weigh 35–60 lbs, while females weigh 29–52 lbs. Both sexes stand 17–23 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 Portuguese Water Dogs 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 Portuguese Water Dog Overweight?

To determine if your Portuguese Water Dog is at a healthy weight (35–60 lbs target):

  • Rib test: You should be able to feel the ribs without pressing hard, with a thin layer of fat covering them
  • Waist check: Viewed from above, there should be a visible waist behind the ribs
  • Tuck-up: From the side, the abdomen should tuck up behind the rib cage

Their curly coat can mask weight gain, so hands-on assessment is essential. If your Portuguese Water Dog is overweight, work with your veterinarian to develop a safe weight loss plan. Even a 10% reduction can reduce the risk of Progressive Retinal Atrophy and other conditions.

Portuguese Water Dog Weight Management Tips

Maintaining your Portuguese Water Dog at a healthy weight between 35 and 60 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 Portuguese Water Dog'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 Portuguese Water Dog 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 Portuguese Water Dog 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 Portuguese Water Dog: 0.5–1.2 cups of high-quality dry food in two meals, budgeting $60–92/month. Puppies growing toward 35–60 lbs need three to four daily feedings until around six months old. DNA testing has dramatically reduced inherited diseases in the breed; responsible breeders test for PRA, JDCM, and GM1 storage disease before breeding.—treats count toward daily calorie intake.

Health Risks of Incorrect Weight in Portuguese Water Dogs

Both underweight and overweight conditions pose serious health risks for the Portuguese Water Dog. Understanding these risks reinforces the importance of maintaining your dog within the 35–60 lb target range.

Overweight risks: Excess weight places additional strain on joints, increasing the risk and severity of conditions like Progressive Retinal Atrophy. Overweight Portuguese Water Dogs 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 Portuguese Water Dog 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 Portuguese Water Dog appears thin despite normal feeding, veterinary examination is essential to rule out medical causes.
