Bring Your Dog to Seattle Mariners Bark at the Park — September 3

If your co-pilot has been dreaming of a night out that ends with a victory lap, this is the one. On Thursday, September 3, 2026, the Seattle Mariners close out their 2026 Bark at the Park series at T-Mobile Park in Seattle, Washington — and it finishes with a postgame walk around the bases with your dog. First pitch against the Athletics is 6:40 PM PT, and leashed dogs settle in with their people in a designated section.

T-Mobile Park sits at 1250 First Avenue South, just south of downtown, and this is the final dog date on the Mariners' 2026 calendar (the earlier ones — April 20, May 18, June 29, and August 4 — have already come and gone). That last-chance status plus the base-path stroll is exactly why these tickets sell out well ahead of time.

What to know before you go

From the event's own listing: a separate dog ticket is required alongside a human ticket, leashed dogs sit with their owners in a designated section, and the night wraps with a postgame walk around the bases. Prices, sections, and any waiver requirement are set by the club, so confirm the current details with the Mariners before you buy — and buy early, because this date moves fast.

Ballpark tips for a happy dog

A ballpark is a big sensory day for a dog. A little prep goes a long way:

• Standard leash on at all times — leave the retractable at home for tight seating and a crowded base-path walk.
• Bring a collapsible bowl and offer water often; even a mild Seattle evening earns a hydration break.
• Scope out shade and the nearest exits when you arrive, and give your dog a cool place to lie down.
• On warm days, mind the concourse pavement — too hot for your palm means too hot for paws.
• Pack high-value, low-mess rewards to keep your dog dialed in through crowd noise. Our freeze-dried dog treats are single-ingredient and crumb-light — easy to slip into a pocket for the base-path lap.
• Never leave your dog in a parked car before or after the game, even briefly.

Worth repeating from the listing: a separate dog ticket is required alongside a human ticket, leashed dogs sit with their owners in a designated section, and the evening includes a postgame walk around the bases. Confirm price, section, and any waiver requirement with the club before you travel.
