I made a spreadsheet of North American carriers and WestJet's hold allowance was the standout: 45 kg including the kennel, which is genuinely large-dog territory. Luna disapproves of taxiing and would never need that much. The column I'd flag is the booking one, because WestJet words it as a warning rather than a deadline, and warnings are easier to misread.

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.

WestJet states that if you do not request space for your pet 48 hours before departure, space may not be available and you may not be permitted to travel with the animal. It is phrased as a risk rather than an absolute cut-off, but the outcome is the same when the hold is full. Request the space when the flight is booked.
So WestJet: 45 kg in the hold including the kennel, and a 48-hour request window that is described as a risk rather than a rule. For a large dog that allowance is the headline number on this page — most carriers stop well short of it. Build a personalized plan and we'll compare the kennel weight against every carrier on your route before you commit to one.
