Toronto to Miami with a dog in 2026: what decides it
A cross-border flight puts two separate gates in front of you: the airline, then US entry. Here is how each one works on this route, and what to sort out before you book.

Key takeaways
The airline gate
Most carriers on this route take a small dog in the cabin for a fee, with the pet and carrier together capped at roughly 20 to 22 lb. Air Canada allows 22 lb and, since June 2025, soft-sided carriers only, with agent check-in rather than online. WestJet also allows 22 lb, wants the pet booked at least 48 hours ahead, and counts the carrier as your personal item. Delta, American and United sit at 20 lb, and JetBlue takes small dogs and cats only, capped at six pets per flight.
Two carriers are worth knowing about before you shop on price. Porter carries no pets in the hold at all and allows just two in the cabin across the whole aircraft, so book early or not at all. Flair carries pets in the cabin on flights within Canada only, which rules it out for this route entirely.

The US entry gate
Because this is a cross-border trip rather than a domestic hop, entry requirements apply on top of whatever the airline says. That means rabies documentation, identification that matches the record, and in most cases a certificate issued inside a set window before travel, which is why booking early and getting paperwork early are two different tasks.
The United States and Canada corridor is the one WayFur checks most thoroughly, in both directions, so a check on this route returns real requirements rather than a general reminder.

What to settle before you pay
Confirm the carrier takes your dog by breed as well as by weight, add the pet to the booking inside the carrier’s notice window, and check the vaccination dates against your travel date rather than against today. If any of those three fails, it is far cheaper to know before the ticket than at the counter.

Common questions
Can I fly from Toronto to Miami with my dog?
Usually yes, but two things decide it. First, the airline: cabin eligibility depends on your dog's breed, weight and carrier size, and some carriers refuse flat-faced breeds outright. Second, US entry: crossing the border means rabies documentation and paperwork issued inside a specific window. WayFur checks both against the airline you pick and your travel date.
Is my dog too big for the cabin on this route?
Most carriers on it cap the pet and carrier together at roughly 20 to 22 lb, and the carrier has to fit under the seat. Above that, the dog needs a carrier that offers a hold service, and several do not offer one at all.
How far ahead do I need to book the pet?
Sooner than you would think. Several carriers cap the number of pets on a flight and ask for 24 to 48 hours notice, so the seat can be available when the pet space is not.
