What My Dogs Taught Me About Love, Loss, and Growing

Some dogs just show up in your life. And some dogs arrive.
I’ve come to believe there’s a difference. The ones who just show up are wonderful, but the ones who arrive? They come with a purpose. They come to give you something, or teach you something, or remind you of something you forgot about yourself. You don’t always know it right away. Sometimes you only see it looking back.
I’ve had three dogs who arrived with purpose. And I’ve started to think of them in a specific way, a framework that didn’t come from a book or a training course, but from living alongside them.
The Heart Dog.
Spike was an old soul. You could just tell. Some dogs are young and wild and figuring it out, Spike came into the world already knowing something. There was a wisdom in him, a steadiness, and underneath it all an almost endless amount of love to give. He made sure my heart was full. That was his job, and he took it seriously.
We had seven years together. Seven years that were somehow both too short and completely full. When I lost him, I understood for the first time what people meant when they said grief and love are the same thing wearing different clothes.
Spike taught me what it means to be chosen by a dog. Really chosen. And when he was gone, he left a shape behind, an outline in my life that nothing else would ever quite fill. Not because I couldn’t love again, but because that space was specifically his.
He was my heart dog. And heart dogs don’t get replaced. They just make room.

The Soul Dog.
Annie is a spicy girl. Let’s just get that out there. She has opinions, she has energy, and she is not shy about either. But that fire in her? It turns out that’s exactly what I needed.
She got me through some of the hardest seasons of my life, the passing of my dad, and a medical condition that left me unable to do much for a long time. During those days, Annie never left my side. When I felt unstable, she would lay on me, not beside me, on me, like she was physically anchoring me to the earth. Like she knew her weight was what I needed to feel safe.
And then, when she sensed I’d been still long enough, she would push me. Nudge me off the couch. Insist on movement, on life, on getting up one more time. She knew when I needed comfort and she knew when comfort had become hiding. She called me out with love every single time.
That’s the thing about soul dogs. They don’t just fit into your life, they tend to it. Annie is a piece of my soul walking around outside my body, and she has protected that soul fiercely when I couldn’t protect it myself.
She is five now, and she is my person. My anchor. My soul dog.

The Growth Dog.
And then there’s Ace.
Ace is six months old and he is a complete and total goofball. He is the teenager who only wants to have fun, who bounces through life like the world is one big game, and who couldn’t hurt a fly even if he tried. He is pure, joyful, chaotic good.
But underneath all that silly, bouncing energy lives one of the softest souls I’ve ever met. He feels everything. He wants connection, he wants to get it right, and when he knows he’s made you smile he lights up from the inside out. The goofball exterior is real, but so is the tenderness underneath it. He is both things completely.
And he is absolutely, completely, on purpose, here to teach me something.
He is testing my patience in ways I didn’t know I had left to be tested. He is asking me to be kind when kindness is hard, when the patience is thin and the day is long and the goofball has done something spectacularly goofball. He is relentless in the way that only puppies and great teachers can be.
But here’s what I’ve realized about Ace: he doesn’t just teach me patience and kindness passively. He requires them. Because he won’t thrive without them. He is holding me accountable to my own growth in real time, every single day. I can’t phone it in with him. I have to actually show up, soft, steady, and present, or we both feel it.
He is my growth dog. And I think he knew exactly what he was doing when he picked me.

The Invitation.
I wonder if you have them too, the heart dog, the soul dog, the growth dog.
Maybe you’ve had all three across a lifetime of loving dogs. Maybe you’re in the middle of one of these chapters right now and you didn’t have words for it until this moment. Maybe you’re deep in the growth dog season, exhausted and stretched and being made better against your will, and you just needed someone to tell you that it means something.
It means something.
They always arrive for a reason. We just have to be paying attention.
