I was getting ready to rehome him. I hate admitting that, but I was running on four hours of sleep for a month.
His name is Bruno. He’s a 70-pound Boxer mix, and like clockwork, every single night at 3:15 AM, he would wake up. He wouldn't bark. He would pace. Noisy, frantic pacing on the hardwood floors outside my bedroom door. Up and down the hallway. Sniffing the baseboards. Whining low in his throat.
I tried everything. More exercise. Calming treats. Crating him (he broke out). "He's neurotic," my vet suggested. "Maybe it's canine dementia."
Last Tuesday, I snapped. At 3:17 AM, I threw off the covers, furious. I was going to put him in the garage just so I could sleep.
I opened the door. Bruno wasn't pacing. He was standing frozen in front of the utility closet door at the end of the hall. His whole body was vibrating.
"What is your problem?" I whispered angrily. I grabbed his collar to pull him away. He refused to move. He looked at me, then looked at the door, and let out a sharp bark.
I smelled nothing. I heard nothing. But his intensity scared me.
Just to prove him wrong, I opened the closet door. It held the furnace and water heater. Still nothing.
But Bruno wouldn't cross the threshold. He backed away, growling at the dark corner behind the furnace.
I called the gas company at 4:00 AM. I felt like an idiot. The technician arrived an hour later, grumpy and tired. He waved his scanner around.
The scanner immediately started shrieking.
"Get out of the house," the technician said, his face pale. "Right now."
There was a micro-fracture in the main gas line hidden behind the wall. It was leaking carbon monoxide—colorless, odorless, and deadly. It wasn't enough to trigger the detector yet. But it was enough for a dog's nose.
If Bruno hadn't woken me up—if I had just put him in the garage—I wouldn't have woken up at all.
I look at the garage door now and my blood runs cold. I was minutes away from locking my guardian angel in the dark just so I could get some sleep.
I was annoyed by his love. I was angry at his persistence. And he just took it. He took my frustration, he took my yelling, and he kept warning me anyway. Because that’s what dogs do. They don’t care if you’re grumpy. They don’t care if you’re tired. They only care if you’re safe.
Tonight, when he starts his rounds at 3:00 AM, I won’t sigh. I won’t roll over. I’ll get up, kiss his big, velvety head, and thank God that while I was blind, he was watching.
We don't deserve them. We really, really don't.
