Nathaniel DiRenzo Answers: Top Dog Training Questions from Pet Parents

If you've ever found yourself Googling “how to stop my dog from barking at the mailman” or “why does my puppy eat everything in sight,” you're not alone. Pet parents across the country face similar challenges, and few people are better equipped to help than dog behavior expert Nathaniel DiRenzo.

Known for his balanced, no-nonsense approach to training and deep empathy for both pets and their humans, DiRenzo has become a trusted name in the dog training community. Whether you're dealing with a hyperactive puppy, a stubborn older dog, or just looking to improve communication with your furry friend, Nathaniel has the answers. In this blog, he tackles the most common (and confusing) questions dog owners ask.

Q1: How Do I Get My Dog to Stop Pulling on the Leash?

Nathaniel: “Leash pulling is one of the most common issues, especially with high-energy breeds. The key is consistency. Every time your dog pulls, stop walking. Only move forward when the leash is loose. You’re teaching them that pulling gets them nowhere—but calm walking gets them where they want to go.”

He also emphasizes the importance of the right gear. A well-fitted harness or head collar can make a huge difference while you're reinforcing good behavior.

Q2: My Dog Doesn’t Come When Called. What Can I Do?

Nathaniel: “Recall is a life-saving command. But too many pet parents accidentally poison the word ‘come’ by using it when something negative follows—like ending playtime or giving a bath.”

His tip: make “come” the best word your dog hears all day. Use high-value treats, toys, or praise, and never use it for punishment. Practice in distraction-free areas first, then gradually increase the challenge.

Q3: How Do I Stop My Dog from Barking Excessively?

Nathaniel: “First, figure out the ‘why.’ Is it boredom, anxiety, territorial behavior, or just pent-up energy?”

He recommends structured exercise, mental stimulation (like puzzle toys), and training alternative behaviors. “You can’t just tell a dog ‘no’—you have to give them a ‘yes’ behavior to replace it with.”

In some cases, working with a professional to address deeper anxiety issues is the best path forward.

Q4: My Puppy Bites Constantly. Is That Normal?

Nathaniel: “Yes—and no. Puppies use their mouths to explore the world, but they need to learn bite inhibition.”

He suggests redirecting with chew toys and using a consistent “ouch” to mimic the feedback they’d get from littermates. “Never punish or yank your hand away aggressively. You’re teaching control, not fear.”

Q5: Can an Old Dog Really Learn New Tricks?

Nathaniel: “Absolutely! Dogs are lifelong learners. Older dogs may need a bit more patience, especially if unlearning bad habits, but they’re very capable.”

In fact, training older dogs can be easier in some ways—they're often more focused and less hyper than puppies.

Q6: How Do I Get My Dog to Stop Jumping on People?

Nathaniel: “Dogs jump because they’re excited and want attention. Unfortunately, even pushing them away is rewarding—it’s still attention.”

Instead, he teaches owners to ignore jumping completely and only reward four paws on the floor. “Be consistent. No petting, eye contact, or talking until they’re calm.”

Q7: What’s the Biggest Mistake Pet Parents Make?

Nathaniel: “Inconsistency. Dogs thrive on clear rules and predictable consequences. If one day jumping is ignored and the next day it’s tolerated, you’re confusing your dog.”

He also warns against relying too heavily on treats. “Rewards should eventually shift to praise, play, or freedom—things that happen naturally in daily life.”

Q8: When Should I Seek Professional Help?

Nathaniel: “If your dog shows signs of aggression, intense fear, or if you feel overwhelmed, don’t wait. Professional guidance can prevent small issues from becoming dangerous or unmanageable.”

He encourages pet parents not to feel ashamed or like they’ve failed. “Training is a skill, just like parenting. No one’s born knowing how to do it perfectly.”

Final Thoughts

Nathaniel DiRenzo’s approach to dog training isn’t about dominance or control—it’s about building a relationship based on trust, consistency, and communication. His advice is rooted in real-life experience and a deep respect for both dogs and their people.

Whether you’re a first-time dog owner or a seasoned pet parent, the journey of training your dog is also a journey of personal growth. And with experts like Nathaniel guiding the way, you’re never walking that path alone.

So next time your dog ignores your command, barks at a squirrel, or turns your living room into a racetrack—take a breath, stay calm, and remember: your dog isn’t being bad. They’re just being a dog. And with the right approach, they can learn anything.
