If you're up for the drive to Vancouver, BC (I believe it's a 3 hour drive from Lakewood, WA - with the exchange rate, it'd be a steal for you
)...many local pet store boutiques sell the buddy belt and I've seen all sizes that your pup can try on in store. Your pup just needs an up-to-date rabies certificate to pass the border. Let me know if you'd like pet store recommendations.
