Dogs’ expected lifespans can vary significantly depending on their breed. One key factor that can influence a dog’s lifespan is their weight, meaning that generally, smaller breeds tend to live longer than heavier breeds.

So, how long do Portuguese Water Dogs live? They are a breed with a fairly long estimated lifespan of 11–13 years, and they tend to maintain a high quality of life. However, their longevity largely depends on the individual dog’s health status, genetics, and how well they’re cared for. Let’s dive in (pun very much intended) into the Portuguese Water Dog’s life expectancy and important factors to take into account.

What’s the Average Portuguese Water Dog Lifespan?

The average life expectancy of a Portuguese Water Dog is between 11 and 13 years, but some very lucky and healthy Portuguese Water Dogs live even longer than this. For comparison, here are the average lifespans of a few other popular dog breeds:

Labrador Retriever: 11–13 years
Golden Retriever: 10–12 years
Poodle: 10–18 years
German Shepherd: 7–10 years
Dachshund: 12–16 years

Why Do Some Portuguese Water Dogs Live Longer Than Others?

A dog’s lifespan will depend on various factors that have an effect on overall health. Major factors include:

Nutrition

Proper nutrition is key to preventing health issues like obesity and nutritional deficiencies. A complete and balanced diet from a reputable brand, coupled with enough exercise, can help to ensure your Portuguese Water Dog develops properly, stays in good shape, and feels well overall.

Environment and Conditions

Dogs living in unsanitary or otherwise unsafe conditions are more prone to becoming sick, getting injured, or even killed due to health and safety oversights. For example, if a dog is allowed to roam freely in a poorly secured yard that gives out onto a road, they could very easily get into an accident.

The correct living environment for a dog is one that is secure and comfortable. They should also be provided with plenty of affection and mental stimulation.

Genetics & Breeding History

Sometimes, a genetic (breed-specific) condition can affect a dog and affect their lifespan and/or overall quality of life. If a breeder is reputable, they will perform screenings to check for genetic health conditions.

Some of the health conditions that have been linked to Portuguese Water Dogs include progressive retinal atrophy, cataracts, hip dysplasia, patellar luxation, dilated cardiomyopathy, and hypoadrenocorticism (Addison’s disease).

The 4 Life Stages of a Portuguese Water Dog

1. Puppy

Dogs are considered puppies until they’re 6–9 months old. This is a crucial stage for socialization, as the younger the dogs are, the more receptive they are to socialization and training.


2. Young Adult

Young adult dogs are from 6–9 months old up to 3–4 years of age. Your dog will become fully grown physically and should be fully socially mature by the end of this stage. They’ll likely still have plenty of energy as young adults.

3. Mature Adult

When a Portuguese Water Dog finishes their physical and social maturation when they reach 8–10 years of age, they’re in the mature adult stage. They may still be energetic but slow down a bit, though this depends on the dog—some remain puppy-like into adulthood and even into their senior years!


4. Senior

This period marks the final 25% of the dog’s average lifespan, in the case of Portuguese Water Dogs, it would be approximately 8–10 years old.

How to Tell Your Portuguese Water Dog’s Age

If you’ve adopted a Portuguese Water Dog and don’t know their age, you can ask your vet for an estimation. Factors that contribute towards an age estimation include the health and shape of the teeth, color of the coat, energy levels, eye appearance, and general health status. Let’s break this down further.

Younger dogs tend to have whiter teeth which maintain the fleur-de-lis shape in their incisors. An older dog may also display dental wear and tear, staining, and tartar buildup, but this depends on how well the teeth have been cared for. Older dogs may also develop gray hairs (though this, too, can happen in younger dogs) and cloudiness in their eyes. They may also have lower energy levels.

Conclusion

In conclusion, the expected Portuguese Water Dog’s lifespan is pretty good—not as long as some breeds, like Poodles, for instance, but these figures are just estimations.

A healthy, happy Portuguese Water Dog with access to proper healthcare could live up to 15 and beyond. Don’t forget to take your dog for general vet checkups every 6–12 months to keep an eye on their health and get any health conditions diagnosed and treated as early as possible.
