What I can do for you

Five ways I look after your pet

Happy companions

The dogs I get to spend my days with

Every one of these is a dog I look after — on a walk, on the couch, waiting for a ball. It's the same kind of photo you'll get from me while you're away.

Meet your pet sitter

It's just me. Always me.

I'm Cory Brennan, and K9 Companions is my own business — no team, no outside staff, no rotating faces at your door. If you book me, I'm the one who shows up.

I've been caring for pets for over ten years, and I handle every visit and every overnight stay personally. Your pet gets one person who knows their name, their quirks, and the way they like their dinner.

Clients usually want to know one thing before they book — will I keep them posted? Yes. Photos and updates are a big part of the service, not an extra.

From first message to first walk

Simple, and no surprises

01
Tell me about your pet
Send a booking request with your dates, times and your pet's name. It comes straight to me, and I reply with availability and an exact price.
02
We meet first
A short meet-and-greet at your home, so your pet meets me while you are there. I make a note of food, quirks and hiding spots.
03
I take it from there
You leave the instructions; I follow them exactly. Then a photo and a short note each visit, so you never have to guess how it went.
04
Home to a happy pet
You come back to a pet who stayed in their own house, on their own schedule. Same sitter next time, so nothing has to be relearned.

The question I get most

“Will you send me pictures while I'm away?”

Absolutely — every visit. A photo of your dog on the walk, your cat where they actually spent the afternoon, a note about how they ate and whether they were themselves. You don't have to ask how they're doing; you'll already know.
