WestJet just earned a spot on my adventure shortlist, and here's the headline: dogs ride in the cabin, so Nala doesn't have to leave my side on the way to the next trailhead. Sam and I love a carrier that keeps our high-energy pup close and calm. If you're plotting a big outdoor escape with your dog, this route is worth a serious look. Let's go.

WestJet's pet policy splits into cabin and cargo. This page summarizes the weight limits, fees, brachycephalic-breed restrictions, and carrier specifications for both modes — sourced from the airline's official pet pages.

Book cabin space at least 48 hours before departure. Reserve early because cabin spots are limited and fill fast. Confirm the reservation directly with the airline once the seat is held. Missing the 48-hour window can push a dog off the flight entirely. Add a calendar reminder two days ahead and complete the booking before any other trip logistics get finalized.
Cargo carriage stops when temperatures cross the 15 °C heat threshold. Check the forecast at the departure airport, connecting stops, and the destination against that 15 °C ceiling. Book early-morning or late-evening flights to stay under the limit during warmer months. Warm-season routes may block cargo travel outright, so confirm the shipping window before purchasing any ticket.
So there's your WestJet trailhead map: cabin, cargo, and hold all open, microchip locked in, and Sam already eyeing the next mountain route. Every dog and destination is its own puzzle, though, so don't wing the details. Build your personalized plan with Pawgo's plan-builder and get the exact requirements for your actual trip mapped out before you pack. Bring more water than you think, and go chase that adventure.
