Welcoming guests into your home should be an enjoyable experience, but for Nyx, a 75-pound mixed breed dog, it was a source of intense anxiety. His fear-based reactivity led to jumping, mouthing and even snapping at visitors—leaving his owners feeling overwhelmed and out of options.
By implementing a structured, compassionate training program, Nyx transformed from an anxious greeter into a calm, confident companion and host.
Here’s how we made it happen.
The Challenge: Fear-Based Reactivity Toward Guests
Nyx displayed significant distress when visitors entered his home. His initial response was to rush toward them, jump up and mouth their clothes and body.
His actions often escalated into snapping, leaving guests with scratches and torn clothes. While he never nipped beyond a Level 2 on the Dunbar Dog Bite Scale* (scratches but no punctures), Nyx's behavior was intimidating and stressful for both his owners and their visitors.
Adding to the challenge, Nyx’s family lived in a tiny apartment with limited space for separation and Nyx had a history of negative experiences with crating so that wasn't an option either. While we had previously successfully worked on Nyx's reactivity to dogs on walks, his indoor guest-related behaviors felt overwhelming and impossible to manage to his parents.
The Training Goals
Help Nyx feel comfortable and safe when visitors arrived.
Teach his parents to recognize early signs of anxiety.
Establish a predictable routine to set Nyx up for success.
Introduce a new, desirable behavior to replaced his reactive response.
Reduce overall stress through daily enrichment & confidence building activities.
A Customized Reactivity Training Plan
Nyx’s parents committed to a two-month in-home private training program designed to build his confidence and reduce his reactivity. Before starting, Nyx had been on Fluoxetine (a medication for anxiety) for five weeks, giving him a more stable emotional foundation for learning.
Step 1: Suspended Visitor Access & Foundation Training
To allow Nyx to reset, we temporarily paused guest visits. This break prevented continued exposure to his trigger, helping him feel safe enough to learn new behaviors.
We chose “place” as his new go-to behavior when guests arrived. Since Nyx was already familiar with the cue, we began reinforcing "place" with high-value rewards. When given the "place" cue, Nyx would go to his comfy bed to hang out until released. His parents practiced extensively, increasing the amount of time Nyx spent on his bed. When Nyx was ready, they also gradually introducing distractions with the goal of ultimately having Nyx be able to stay on his "place" when visitors were over. His parents also learned to read Nyx’s body language to recognize early stress signals as the best time to intervene in a dog's over-reaction is before it even happens.
Step 2: Desensitize to Trigger & Counter-condition
Once Nyx was confidently staying in his “place” when asked, we addressed his emotional response to guest-related triggers.
Hallway Sounds: We paired the sound of people in the hallway with high-value treats, teaching Nyx that these noises predicted something good.
Door Knocks: We introduced knocking sounds while rewarding Nyx for staying relaxed on his bed.
Door Opening: Gradually, we worked up to opening the door without anyone entering.
Through repetition, Nyx learned that these once-stressful events were safe.
Step 3: Reintroducing Visitors in a Controlled Manner
With a strong foundation in place, we introduced an actual guest—me!
Initially, Nyx was leashed for safety.
I entered calmly and ignored Nyx.
Nyx was rewarded for remaining in his “place” with high value enrichment activities like his lick mats and chews.
As Nyx's confidence grew, we repeated the above process with him off-leash.
Over time, Nyx learned that visitors not only weren’t a threat but they predicted positive experiences for him like yummy peanut butter on a lick mat. His automatic response became relaxation instead of reactivity and his parents could once again have friends over.
Step 4: Pre & Post Guest Visit Routines
To maintain Nyx’s progress, his parents followed structured routines before and after having guests over:
Pre-Visit: Nyx got a relaxing sniffy walk and a few practice runs of “place.”
During Visit: Visitors followed house rules to ignore Nyx until he settled and he engaged in enrichment activities instead of focusing on them.
Post-Visit: Decompression time! Whether through napping, enrichment or belly rubs Nyx had the chance to release any stress he may have built up during the visit.
These predictable steps helped Nyx feel secure and reinforced his new calm behaviors.
The Transformation: A More Confident, Relaxed Dog
Nyx’s parents were dedicated to the process and their efforts paid off!
They reported: “He [Nyx] was so much calmer when hearing any noise in the hall and even seemed happy to have regular visits from people he recognized. He is so much more responsive to our directions that it has even improved his behavior outside of the house.”
Nyx now comfortably remains in his “place” while guests are over. If he becomes uncertain, his parents quickly recognize the signs and redirect him back to his enrichment activity (usually a filled Kong, lick mat or other chew) and he happily settles back down.
Thanks to their commitment, Nyx's parents could finally welcome friends and family into their home in a way that was stress-free for all.
Key Takeaways for Dog Parents with Reactive Pups
Suspend triggers while building new behaviors – Giving your dog space to learn without repeated stress is crucial.
Choose an alternative behavior that fits your environment – “Place” worked for Nyx because it was already familiar and adaptable.
Use desensitization & counterconditioning – Rewarding calm behavior around triggers changes your dog’s emotional response.
Practice with low-stakes scenarios before introducing real guests – Training with controlled setups provides safety and prevents setbacks.
Stick to predictable pre/post-visit routines – Structure and consistency make all the difference.
Nyx’s journey is proof that with patience, commitment and the right approach, reactive dogs can learn to feel safe and thrive in their homes. If your dog struggles with similar challenges, professional guidance from a positive trainer with experience working with reactive dogs will set you on the path to success.
