My Dog Bit Someone and I Can't Remember His Last Vaccination Here's What Saved Us

We were at the park our regular morning circuit before the world gets too loud when my dog, Theo, a goofy, 65-pound rescue with a golden heart and occasional gremlin energy, lunged forward and snapped. It was quick. A blur. One second he was sniffing a leaf, and the next, a yelp rang out from a jogger who’d come up behind us.

Theo had bitten someone. And I couldn’t remember the date of his last rabies vaccine. The world kind of stopped spinning for a beat.

When Your Worst Fear Happens in Broad Daylight

The woman clutched her arm, eyes wide and shocked. Thankfully, the skin wasn’t broken, but there was a red welt clear contact had been made. I went into full apologies, asking if she was okay, offering my number, my vet’s number, anything I could do. She nodded and waved me off, clearly rattled but not confrontational. Still, my heart was jackhammering.

And that’s when it hit me I could not remember the last time Theo had his rabies booster.

I felt the edges of panic creep in. Because this wasn’t just about the bite. It was about what the bite represented. Had I failed my dog? Had I put someone else at risk? Was Theo now officially “a dangerous dog”? Would this moment undo all the progress we’d made?

Why Dogs Bite and Why It Doesn’t Mean They’re “Bad”

Let’s talk about it. Dog bites are one of those taboo topics that make us drop our voices and avoid eye contact. It’s the thing every dog parent silently fears: the loss of control, the label, the guilt.

But here's the thing dogs bite for a reason. Always. Whether it’s fear, pain, over-arousal, or surprise, there's a root cause that can be unpacked. In Theo’s case, I now realize the jogger had startled him. She came up fast from behind, and he probably felt cornered. Was it okay? Of course not. But it wasn’t random or malicious. It was communication, not cruelty.

We tend to label dogs as “bad” or “aggressive” when they bite, but that’s as unfair as calling a kid bad for crying when they’re scared. Biting is a last-resort behavior, and often a sign that we’ve missed quieter cues like the tucked tail, the lip lick, the freeze.

The Training Side: What I Missed (and What I Learned)

Looking back, the signs were there.

Theo had always been a little reactive to fast movement. Skateboards. Joggers. That one mail carrier with the clompy boots. We’d made so much progress using positive reinforcement clicker training, high-value treats, building his confidence around “scary” things. But on that particular day, I broke the cardinal rule of training: I got comfortable.

I assumed he was “over it.”

What I should’ve done instead? Managed the environment better. We could’ve gone to a quieter trail. I could’ve stayed more engaged, maybe had him work on “watch me” or “find it” games to keep him focused. I could’ve anticipated his triggers.

But training is never a straight line. It’s a series of loops and detours and two-steps-forward-one-step-back moments. Dogs, like us, are works in progress.

Practical Tips to Prevent and Prepare for Bite Incidents

If your dog has ever growled, snapped, or reacted unpredictably or if you simply want to be proactive here’s what I’ve learned from both personal experience and years as a trainer:

1. Know your dog’s triggers

Keep a mental (or physical!) log of what sets your dog off. Is it men in hats? Children running? Squeaky bikes? Knowledge is power.

2. Train for real-life scenarios

Use positive reinforcement to gradually expose your dog to low levels of their trigger. Reward calm behaviour, build distance, and take your time.

3. Use management tools

There’s zero shame in using a well-fitted muzzle, especially for dogs in training. It protects both your dog and the people around you, and it can give you peace of mind. (Theo now wears one during busy times, and honestly? He looks kind of badass.)

4. Always carry high-value treats

Have something irresistible like chicken or cheese in your pocket. You never know when you’ll need a distraction or quick redirection.

5. Have your medical ducks in a row

Keep your dog’s vaccination records up to date and accessible. I now store Theo’s in a cloud folder and in my phone. You don’t want to be mentally flipping through last year’s calendar while adrenaline is surging.

What Actually Saved Us

That afternoon, I called my vet in a total spiral. Theo’s last rabies vaccine had just expired literally a month prior. But because he had been vaccinated consistently over the years, the vet reassured me that his immunity wouldn’t vanish overnight. She also guided me through the post-bite protocol: we filed a report, documented the incident, and scheduled a booster right away.

The jogger, bless her heart, texted the next day to say she was fine and appreciated my response. No legal action. No drama. Just two humans and a dog who had a very bad moment.

What saved us? Preparation, honesty, and a community of professionals who didn’t judge. And a dog who, despite this slip, is still very much the goodest boy.

When You Feel Like You’ve Failed Your Dog

That night, I curled up next to Theo, ugly-crying into his fur. He snored peacefully, blissfully unaware of the emotional wreckage he’d caused.

I felt like I’d let him down. That I hadn’t protected him from the situation. That I hadn’t trained him “enough.”

But then I remembered what I so often tell my clients: You are not your dog’s mistake. And your dog is not the sum of one bad moment. We are all learning. Every snarl, every scared reaction, every hiccup in training it’s all information. It’s all part of the story.

Progress Isn’t Linear and That’s Okay

If you’ve been through something similar, please know this: you are not alone. So many of us have these secret, scary moments that we’re too ashamed to talk about. But sweeping them under the rug doesn’t help our dogs or ourselves.

Talk to your vet. Reach out to a certified positive reinforcement trainer. Join a support group if you need to. Let’s normalize these conversations and move forward together, as a team.

From One Dog Lover to Another

Dogs don’t come with guarantees. Even the sweetest soul can have a bad day. What matters is how we show up the next day how we advocate for them, protect them, and teach them with patience and love.

So if your dog has ever growled, nipped, or made you question your ability as a pet parent, come sit next to me. I’ve got coffee, a worn-out clicker, and a heart full of empathy. Let’s figure it out together.

And maybe just maybe let’s double-check those vaccination dates.

If you ever find yourself in a situation where you need fast, reliable veterinary guidance whether it’s about vaccinations, post-bite protocols, or simply calming your own nerves Vets and Care is a great resource. Their online platform connects you to licensed vets for real-time support, so you’re never left second-guessing when it matters most.
