The 4 Life Stages Of The Newfoundland Dog

There are two terms used to describe the Newfoundland that seem to be a double-edged sword with this breed.

These terms are gentle giant and nanny dog.

It’s true that Newfoundlands can be gentle giants and it’s true that Newfoundland dogs can be great with children.

However, many Newfoundlands just don’t come out that way, they evolve into those traits over time.

Before they get there they need to go through the different stages of life.

I’ve been blessed enough to experience the full life of a Newfoundland more than once.

Some of my Newfies went through the 4 stages easier than others.

(Ahem….not Leroy).

These 4 stages are puppyhood, adolescence, adulthood and the senior years.

The Puppy Stage.

Usually from 0-6 months.

What could be better than a bouncy pile of fluff hopping through your house?!

The ginormous paws, the puppy fuzz, the puppy breath I can picture them all in my mind!

This is a fun stage where you get to carry, snuggle, and get to know your new fluffball.

There are naps, there’s playtime, teething, and growing!

In this stage, you get to literally watch your puppy grow overnight and you’re overcome with excitement that you finally have the dog that you’ve always dreamed of.

This is a crucial training period and where you need to start letting your puppy know what behavior is acceptable and what is not before the behavior becomes out of control. 

And there’s potty training and more potty training and more potty training.

The Adolescent Stage.

6 months – 3 years.

Perhaps the stage that you hear the least about because it is the most trying stage of a Newfoundland which is why we have an entire post dedicated to the adolescent stage

It’s the terrible 2’s combined with the teenage years.

Your cute adorable pile of fluff now looks like an awkward, fifty shades of brown/black dork.

The dog is mouthy, clumsy,  and suffers from an acute onset of selective hearing.

You might think that your breeder forgot to add in the gentle giant gene as you watch a 100-pound bear knock over everything that stands its way.

THERE IS NOTHING GENTLE ABOUT THIS STAGE. 

Your Newfie is now finding himself/herself.

They are becoming more independent.

They are full of energy and super uncoordinated.

Like a tornado with 4 legs that bounces off of EVERYTHING.

The only difference between them and any other breed of dog at this stage is that they are MUCH bigger.

They are extremely impressionable at this time and learning their boundaries.

While this may be a trying time it’s also the stage where you’re introducing your Newfie to new things which can be quite fun.

You’re socializing them.

You’re teaching them basic commands.

You are teaching them how YOU want them to behave.

This is the stage where you introduce them to water and let them do their thing.

Towards the latter part of this stage, you might even be introducing them to draft work, therapy work…etc. 

They are a lot of work at this stage and they need to be challenged and stimulated but the work that you put in will be very rewarding in the next stage. TRAIN, TRAIN, TRAIN.

The Adult Stage.

4 years-6 years.

While some adolescent remnants may remain, you now have an adult dog.

Most likely your Newfie has found themselves by now and is settling in.

All your hard work and training is paying off and for the most part, you know what to expect and they know what to expect.

Sure there’s going to be a few more trying times but now it’s time to enjoy the Newfie life.

You can see that gentle giant finally shining through and the angels above start to sing, Hallelujah.

They are finally done growing and their very smart brain emerges once again.

You’re used to going out in public and not getting far because even wants to steal a glimpse of your bear dog.

You begin to understand that a Newfoundland is more than a dog, it’s a lifestyle.

Welcome to this wonderful life.

 

The Senior Stage.

6-? years.

Perhaps one of the best stages because there’s nothing better than the love of an old dog. 

The grey on their muzzle starts to appear and you’re reminded how short life is.

You swear to cherish every single moment. 

I forget about the broken nose you gave me, the time you ran away, the lamps that you broke, now I just want you to be here forever.

They start to slow down, maybe limp a little because their big joints are getting tired.

Instead of long walks, it’s long sitting out in the driveway or a drive to get ice cream.

It’s sweet sugar lip kisses every morning and every night.

It’s belly rubs, massages, and naps.

You begin to transform your house to make life easier for them and you’re always close by in case they need an extra boost.

I think this is the stage when your heart actually swells with love.

Cherish it.

When getting a Newfoundland it’s so important to remember that they go through different life stages.

Very few Newfoundlands start off as a gentle giant or a nanny dog.

Newfies evolve into these traits and every dog is different.

The most trying stage of a Newfoundland is going to be the adolescent stage.

Most Newfies mature slower than other dogs and this can feel like a very long and tiring stage.

This is the stage when a lot of Newfies will end up in rescue because their owners weren’t prepared for a giant adolescent dog.

This is also the stage where I receive a lot of emails from people who are struggling with their Newfie.

You need to put in a good amount of effort in this stage or you’re going to end up with a Newfie gone wild.

I can give you as many tools and suggestions that I have but you have to be able to put in the work and training like the rest of us have done.

There is no easy way out.

If you want the pot of gold at the end of the rainbow, you’ve got to go through the stages to get there.

I’m not putting blame on anyone who is experiencing a tough time with their Newfoundland.

I have a 5-month old puppy that is hitting his terrible twos early.

He looks innocent and adorable and for the most part, he is, but he has a little bit of devil inside of him too. 

In fact, the other day as I was bending down to pick up acorns off the ground he jumped on me, grabbed my ponytail and started shaking it like it was his tug toy.

 

7 years ago Leroy was an adolescent and most of his stories are documented somewhere here.

Now I’m raising Lou and I know we’ll get there and you will too.

p.s. The ranges in the above stages are based on my personal experience.

Individual Newfs may vary.

I adopted my Newfie about 6 months ago. He is 3 years old. Boy had my life changed. No one can prepare you for the hair and drool (which I now call sugar juice). I have only received one black eye so far and I look forward every night having my face covered in drool at 3 am because he decides I need a little loving during the night. Thank goodness I have tile floors. The trail of water every time he drinks is unbelievable (and he drinks a lot). I have gone thru two mops and no matter how hard I try there is drool and soggy footprints all thru my house. I am use to having small dogs that live to be in their teens or 20’s. It breaks my heart that his life span will only be about 10 years. I can’t imagine my life without this gentle giant and I wear my slobber as a badge of honor. Clean freaks beware.

My dog Brinkley is 10 and still is a cheeky monkey, still comes in house like a bull in china shop, quick squit around room, sees it and gone. With with a handbag cushion shoe newspaper anything, even visitors handbags. Well he wants it to all be about him lol. Im worried as he is getting slower and on the pain meds. He will leave a huge whole when he goes.

You couldn’t be more correct. The love of a Newfie is like no other. When you’re walking out the door, and you turn to look at them…. Their eyes say it all. And the minute you say let’s go the eyes light up. The ears go up. They seem to be smiling. And they first have to run and grab a toy. A shoe. A piece of your clothing. Something. The other thing they do or mine anyway. After you feed them. Yogi comes to me puts his head down. Pushes me against something and dies what I call his happy dance. Back and forth on the back legs tail and butt wagging. It’s like he’s saying thank you. Followed by water bowl kisses. Love my Newfie soooooo much.

I had a bronze Newfie. I miss him so much, it's been almost years now. We got him at 3 months with only one eye. He was an amazing boy. I have a million pictures. I agree, he was huge, slobbery, had to go to the groomer for baths and trims and it took me 5 hours to brush on him. He was also kind to all our animals, raised a litter of feral kittens as his own and everybody wanted to touch his bronze furry body. newfies are one of a kind!
