Even vets think that different dog types have different levels of pain sensitivity, even though there isn't much scientific evidence to back this up.
In a study with 10 different dog types, scientists from North Carolina State University found that dogs do have different levels of pain
Veterinarians tend to agree on how sensitive to pain different dog breeds are, and these ratings are often at odds with ratings from the general public.
But it was interesting that the results didn't always match up with how vets think different kinds handle pain.
In the study, 149 adult male and female dogs were divided into three groups based on how sensitive to pain they were: high (Chihuahua, German shepherd, Maltese, and Siberian husky)
average (Border collie, Boston terrier, and Jack Russell terrier), and low (Golden retriever, pitbull, and Labrador retriever).
For example, vet surveys found that Maltese dogs tend to have a high pain sensitivity threshold or low pain tolerance (they respond quickly to stimuli).
Labrador retrievers and golden retrievers have a low sensitivity to pain, so they have always been at the top of the list.
