In order to determine the most pet-friendly places in America, Wallet Hub's analysts compared the 100 most populated cities across three key dimensions: pet budget, pet health & wellness and outdoor pet-friendliness. Wallet Hub evaluated those dimensions using 21 relevant metrics. Each metric was graded on a 100-point scale, with a score of 100 representing the most favourable conditions for pets and their owners, according to the analysts. Finally, Wallet Hub determined each city's weighted average across all metrics to calculate its total score and used the resulting scores to rank-order the cities in our sample. According to this, Scottsdale in Arizona is the most pet-friendly city in America. Phoenix (Arizona) and Tampa in Florida are in second and third places. The last place goes to Newark in New Jersey.
