About Doberman Planet

My name is John Walter and I’m the founder of DobermanPlanet.com. I fell in love with Doberman Pinschers long before I ever owned one. I loved how elegant, strong, and alert they are. Then when I learned how intelligent they were, I found myself even more excited about the idea of owning one someday.

In December of 2012, I bought my first house and I was so excited because this one had a backyard suitable for a Doberman. So in February of 2013, I found a Doberman breeder in the Sacramento area of California who had a new litter of puppies. Both parents of this litter were certified purebred European Dobermans. I was the first to see the litter, so I was able to have the pick of the litter! Each puppy in the litter was wearing a different colored collar.

Soon after arriving, my girlfriend at the time pointed to one puppy with a red collar that would always break out from the pack of his brothers and sisters and come to us when we called out to the group. The red-collared Doberman pup seemed to be incredibly focused on us and time after time, he would be the first to come when we called out for the puppies. My wife knew she wanted that red-collared puppy right away.

I was a little more methodical and insisted on running each puppy through a series of “puppy tests” to see what their individual personalities were like. I scored each pup on a series of tests, added up their scores, and guess which one scored the highest? The puppy with the red collar!

Our New Family Member

We brought home our new Doberman “Cooper” in February of 2013. Since that time, I’ve been enamored with this amazing breed. As a writer, trainer, and avid researcher, I’ve made it my mission to learn as much as possible about the breed, network with other Doberman owners, and spread knowledge about how wonderful these dogs are.

After struggling through the tough puppy stages, my wife and I found ourselves continually growing closer to Cooper as the years

went on. He even had a featured spot at our wedding! We now have our first child and Cooper is full grown and weighs in at about 90 pounds. I’m amazed every day by what an amazing family dog a Doberman can make. Cooper is incredibly gentle with our baby boy, loves being with us at all times, and is very in tune with what we expect of him. We never have to worry about him running off when we take him out somewhere off-leash.

I’ve found Dobermans to be gentle, kind, great protectors, and highly intelligent. They don’t shed much, are easy to take care of, and they just want to be with their family as much as possible. That’s why many people refer to Dobermans as “Velcro Dogs.” They are always stuck to your side!

My Unexpected Adventure Companion

I was really excited to get a loyal protector for my family, especially on nights when I had to work late. Knowing that Cooper was at home with my wife was a big relief. But one thing I didn’t expect, was how great our Doberman would be on the outdoor adventures we take!

We’ve been on multiple overnight backpacking trips with Cooper and every time we’ve been so happy to have him. Not only does he do a fantastic job hauling his own gear with him in his pack, but we never need to have him on a leash, he won’t wander off, and he insists on laying in watch over us while we sleep. Which, when you are out in the woods by yourself, is a really great feeling.

This is what kicked off my love, and passion, for the Doberman breed and it’s why this is the only breed I now work with.

Cooper passed in May of 2019 and he knew nothing but love his entire life, including during the time of his passing.

A New Doberman Came Along… Arlo

In February 2020, after the passing of Cooper, I brought a new European Doberman named Arlo into my home and the homes of millions of viewers. Arlo was an instant hit on YouTube and he’s been featured in well over a hundred videos on our channel. Arlo helped teach the world about everything from preparing for a new Doberman puppy, to potty training, leadership, basic training, and so much more about owning this amazingly unique dog breed.

In February of 2022, the decision was made to retire Arlo from YouTube (see his retirement video here) and focus the channel on the Doberman breed as a whole, and no longer just one Doberman. Arlo’s legacy continues though and many viewers often ask me for an update on him since his retirement.

I released this Arlo update with more information regarding the events surrounding his retirement from YouTube, and his current status.


The areas where I have gained valuable training, knowledge, and expertise is specifically in family relations involving Dobermans.

I do not train IPO/Schutzhund competitors and I do not compete in bite sports. While I believe that these things are great hobbies for some, this is not what a majority of owners are looking for in a Doberman.

Most owners simply want an easy-to-manage, loyal, loving, protective, and gentle family companion who is completely trustworthy in their home environment. This is where my expertise lies. What I enjoy doing more than anything, what gets me up in the morning, is helping people with their Doberman to thrive in a family environment. So, I strive every single day to be the best “Family Doberman Specialist” that I can possibly be.

  • Certified in Canine Communication (CPD certification # KC13O962).
  • Member of the Association of Professional Dog Trainers (Member # 105480).
  • Supporting Member of the IAABC (International Association of Animal Behavior Consultants – Member # 113766).

I use this website or our YouTube channel to report back to Doberman owners worldwide on what I’ve learned through the years and with my ongoing research. I truly love helping other Doberman owners bring these wonderful dogs into their families or their specific living situations.

It’s up to Doberman owners all over the world to spread the word about this wonderful breed! Let’s bring this breed into the mainstream and let the world know what a wonderful family addition a Doberman Pinscher makes!
