Sarah's Shocking Discovery

The Moment I Realized My 4-Year-Old Dog Wasn't Getting Old... He Was Being Poisoned

Published: Friday, October 31, 2025

The day my Golden couldn't keep up on our favorite trail, I knew something was terribly wrong.

Bailey has been my adventure partner for four years. Every weekend, we hit our favorite trail in Queensland. He'd run ahead, circle back, run ahead again. I'd hike 8K while he'd easily cover 15K.

That's who Bailey is. High-energy. Always moving. Born to run.

But a few months ago, something changed.

We were barely two kilometers in when Bailey stopped. Just... stopped. Sat down on the trail. Panting hard.

"Come on, buddy. Let's go." I waited. He didn't move.

I knelt down. Checked his paws. No cuts. No thorns. Nothing obvious. But his eyes looked... tired. Distant.

We turned around. Walked home slowly. Bailey dragged behind me the entire way.

My stomach was in knots. This wasn't my dog.

The next morning, he barely wanted to get off the couch. When I grabbed his leash, he looked at me like even that was too much effort.

I told myself he was just getting older. Dogs slow down at four, right?

But I couldn't shake the fear creeping in at night: What if it's something worse?

How I Almost Lost My Adventure Buddy

I'm Sarah. Marketing manager. Trail runner. And Bailey's mom.

Living near the woods in Queensland, ticks are a big problem. I'd heard the horror stories. Dogs paralyzed, rushed to emergency vets, some not making it.

So when my vet recommended monthly flea and tick treatment, I didn't question it. I wanted Bailey protected. I wanted to be a good dog parent.

Every month, like clockwork, I gave him the treatment. My vet said it was safe. Millions of dogs take it.

I never thought it could be slowly destroying who he was.

The Slow Decline

At first, I didn't see it.

Maybe you won't either. That's what makes this so insidious.

At first, Bailey seemed normal. Maybe slightly quieter, but nothing alarming.

Then he slept a little more. I figured he was tired from our long hikes.

He stopped greeting me at the door with his usual energy. Started needing naps in the afternoon.

After a month, he couldn't even finish a 3K trail without stopping multiple times.

That's when panic set in.

I booked an emergency vet appointment. Ran every test imaginable. Bloodwork. Thyroid. Liver enzymes. Tick-borne diseases.

Everything came back normal.

"Maybe he's just maturing," the vet said. "Some dogs calm down around this age."

But Bailey wasn't calming down. He was fading.

How I Found Out That I Was Poisoning Him

My husband started noticing it too.

"Babe, Bailey's not himself," he said one night. "He used to be bouncing off the walls. Now he barely wants to walk around the block."

I couldn't sleep. Couldn't stop thinking: What if he's dying and I'm missing it?

The next day, I went back to the vet. Different doctor this time.

"Walk me through everything," she said. "Diet, exercise, medications, everything."

"He eats regularly, nothing strange. But he's on monthly flea and tick treatment," I said. "Has been for about four months."

She paused. Looked up from her notes.

"When did you first notice the lethargy?"

I thought back. Then I realized. "Right after I started the treatment I think."

Her expression changed. "That's your answer."

"What are you talking about?" I asked.

She pulled up her computer. Started showing me research. FDA warnings. Studies. Case reports.

"The monthly treatments you're using, the oral and topical ones, they contain chemicals that enter your dog's bloodstream and nervous system. For most dogs, side effects are mild. But for some... it suppresses their energy. Causes lethargy. Neurological changes."

I felt like I'd been punched.

"You're saying the treatment I've been giving him to protect him... is what's making him sick?"

"Yes."

The Protection Dilemma

That night, I couldn't stop researching.

Page after page of results. News articles. Veterinary journals. Facebook groups with thousands of members sharing the same story I was living.

"My Border Collie became a zombie on her monthly treatment. Stopped running. Slept 18 hours a day. Vet told me to stop the treatment and she was back to normal in three weeks."

"I thought my Lab was dying. Turned out it was the flea medication destroying his energy."

"My athletic dog couldn't even walk around the block anymore. The treatment was suppressing his nervous system."

How many dogs are living like this right now? How many owners think their dog is just "getting older" when they're actually being poisoned?

The FDA has issued warnings about neurological side effects. But how many people actually read them? How many vets mention this risk?

I was furious. At myself. At the system. At the fact that I'd watched my best friend fade for months and blamed it on aging.

I stopped the treatment immediately.

But that left me with the bigger problem: paralysis ticks.

Living near the woods, I couldn't just not protect Bailey. Paralysis ticks kill dogs. I'd seen it happen to my neighbors' dog.

I needed protection. But I needed something that wouldn't destroy who Bailey was.

First, I tried natural solutions from the pet store. Sprays. Powders. But within days, Bailey had ticks crawling on him.

Natural wasn't working. But chemicals were killing his spirit.

I was stuck between a rock and a hard place.

But then something unexpected happened at the dog park...

The Dog Park Discovery

I was sitting on a bench, watching Bailey lie in the shade, still too tired to play with the other dogs, when a woman walked over.

"Is he okay?" she asked, nodding at Bailey.

"Long story," I said. "He's recovering from... side effects."

"Oh god, was it one of those monthly tick treatments?" she asked immediately.

I looked up, surprised. "How did you know?"

"My dog went through the same thing," she said. "Couldn't figure out what was wrong until my vet connected it to the treatment."

Her Labradoodle came closer, and that's when I noticed it: a small green pendant hanging from her dog's collar.

"What's that?" I asked.

"It's called FurSure," she explained.

"It's a natural pendant. Clips onto the collar. It slowly releases natural oils like chamomile and citronella, which creates an aromatic shield around your dog. Ticks and fleas smell it and stay away."

I'll admit, I was skeptical. I'd tried natural solutions. They didn't work.

"How is this different from bug sprays?" I asked.

"Sprays wear off in hours. This lasts twelve full months. And it repels pests before they bite, not after. No chemicals entering your dog's bloodstream. It's 100% natural."

She pulled out her phone. Showed me photos of her dog hiking, swimming, running trails. "He's been wearing it for eight months. Not a single tick. And he's got all his energy back after we stopped the monthly treatments."

Something in my gut said: This is it. This is what you've been looking for.

My Honest Results

The pendant arrived a few days later.

Small. Green. Had a lovely herbal scent, nothing chemical. I held it out to Bailey. He sniffed it once, then went back to lying down. Didn't seem bothered by it at all.

I clipped it onto his collar that Friday morning.

And then I waited.

Day 1-3: Bailey still lethargic. No visible change. I tried not to panic.

Day 4-7: Small shifts. He got up a bit quicker. Showed interest when I grabbed his leash. Nothing dramatic, but... something.

Day 10: We attempted a short 3K walk. Bailey made it without stopping. First time in months.

Day 14: I had my dog back.

We went to our favorite trail that Saturday.

I'll never forget it. Bailey bounded out of the car. Pulled on the leash. Ran ahead like he used to.

I cried. Right there on the trail. Because for two months, I thought I was losing him.

We hiked 8K. Bailey ran circles around me. Jumped in the creek. Chased birds. He was alive again. Present. Happy.

This was the dog I knew. The dog those monthly treatments had stolen from me.

And here's the part that still blows my mind: Zero ticks.

After four weeks of using FurSure and hiking the same tick-heavy trails we always do, I did a full-body check at least twice a day.

Not one tick. Not even crawling in his fur looking for a place to attach.

The monthly treatments killed ticks after they bit Bailey. But they still had to latch on first. Still had to feed. We were used to finding dead ticks everywhere.

But FurSure repels them before they ever get close.

And it does it without putting a single chemical into his bloodstream. Without stealing his energy.

I'm not the only one who discovered FurSure...

My dog couldn't finish our morning runs anymore. Vet said it was the monthly treatment. Switched to FurSure and within two weeks, she was back to her old self. No ticks, no lethargy, no guilt. 🐕

These aren't isolated cases. This is happening to thousands of dogs right now.

Most owners don't make the connection. They think: "My dog is just getting older. Calming down."

But that's not what's happening. Their dog is being slowly poisoned by the very thing that's supposed to protect them.

Here's what you need to understand:

If your dog is still energetic on monthly treatments, that's great. Truly.

But it doesn't mean they're not being affected. It just means the effects haven't shown up yet, or they're subtle enough that you haven't noticed.

By the time you do notice, you might not connect it to the treatment.

You'll think it's age. Or diet. Or lack of exercise. You'll run expensive vet tests that come back normal. You'll watch your adventure buddy fade, and you won't know why.

Don't wait until it's too late to make a change.

I Got My Adventure Partner Back

Bailey is sleeping next to me as I write this.

Not the 16-hour zombie sleep he had on monthly treatments.

This is normal, healthy, post-hike sleep. The kind that comes from running 12K through the Queensland bush. From swimming in creeks. From being a dog.

That little green pendant is still clipped to his collar. It's been six months. Zero ticks. Zero fleas. Zero lethargy.

I got my adventure buddy back.

And if I'm being honest? I'm angry it took me so long to figure out what was wrong. Angry that I watched my best friend suffer for months because I trusted that monthly treatments were safe.

But I'm grateful I found FurSure when I did.

Your dog doesn't have to slow down. Not at four. Not at six. Not if the only reason they're lethargic is because of the monthly treatments you're giving them.

Make the choice I wish I'd made sooner.
