Best States for Animals

The U.S. has nearly 3,000 native species of animals, but up to 40% of these animals are at risk of extinction, so more conservation work is necessary. In addition, nearly 87 million households in the U.S. own pets, which rely on our support to survive, and residents of some states take better care of their pets than others.

To highlight the best states for animals and the ones that have the most room for improvement, SmileHub compared each of the 50 states on 18 key metrics. The data set ranges from the number of animal charities per capita to the share of pet-owning households to the number of veterinarians per pet-owning household.

Methodology

In order to determine the best states for animals, SmileHub compared the 50 states across three key dimensions: 1) Pet Ownership, 2) Animal Protection and 3) Animal Wellness.

We evaluated those dimensions using 18 relevant metrics, which are listed below with their corresponding weights. Each metric was graded on a 100-point scale, with a score of 100 representing the highest level of animal-friendliness. For metrics marked with an asterisk (*), the square root of the population was used to calculate the population size in order to avoid overcompensating for population differences across states.

We then determined each state’s weighted average across all metrics to calculate its overall score and used the resulting scores to rank-order the states.

Pet Ownership – Total Points: 30

• Share of Pet-Owning Households: Double Weight (~8.57 Points)
• Share of Rental Properties Allowing Large Dogs: Full Weight (~4.29 Points)
• Share of Rental Properties Allowing Small Dogs: Full Weight (~4.29 Points)
• Share of Rental Properties Allowing Cats: Full Weight (~4.29 Points)
• Annual Cost of Feeding a Dog: Full Weight (~4.29 Points)
• Annual Cost of Cat Food and Kitty Litter: Full Weight (~4.29 Points)

Animal Protection – Total Points: 50

• Animal Protection Laws Ranking: Double Weight (~13.33 Points)
  Note: This metric is based on the Animal Legal Defense Fund’s “Best & Worst States for Animal Protection Laws” ranking.
• Share of No-Kill Shelters: Full Weight (~6.67 Points)
• Animal Save Rate: Full Weight (~6.67 Points)
  Note: This metric is determined by taking the number of animals saved in animal shelters divided by the number of animals entered into animal shelters in each state, based on data from Best Friends Animals Society.
• Share of State Land Designated for Parks and Wildlife: Full Weight (~6.67 Points)
• Number of State Conservation Programs and Initiatives: Half Weight (~3.33 Points)
  Note: This metric refers to the number of conservation programs listed for each state by the U.S. Department of Agriculture’s Natural Resources Conservation Service that directly or indirectly help the animals in each state.
• Animal Charities Per Capita*: Full Weight (~6.67 Points)
• Vulnerability to Climate Change: Full Weight (~6.67 Points)
  Note: This metric is determined by taking the average number of days of climate shift index values of 3 or higher, based on Climate Central data from June 2024 through August 2024. The greater the number of days, the more vulnerable to climate change we consider the state.

Animal Wellness – Total Points: 20

• Veterinarians per 1,000 Pet-Owning Households: Double Weight (~6.67 Points)
• Average Monthly Pet Insurance Cost for Dogs: Full Weight (~3.33 Points)
• Average Monthly Pet Insurance Cost for Cats: Full Weight (~3.33 Points)
• Average Annual Veterinary Cost for Dogs: Full Weight (~3.33 Points)
• Average Annual Veterinary Cost for Cats: Full Weight (~3.33 Points)
