The Civil Rights Division of the U.S. Department of Justice (DOJ) has issued proposed rules to enforce the Americans with Disabilities Act. Specifically, with respect to breeds of dogs used as service animals, DOJ had this to say:
"Breed limitations. A few commenters suggested that certain breeds of dogs should not be allowed to be used as service animals. Some suggested that the Department should defer to local laws restricting the breeds of dogs that individuals who reside in a community may own. Other commenters opposed breed restrictions, stating that the breed of a dog does not determine its propensity for aggression and that aggressive and non-aggressive dogs exist in all breeds.
"The Department does not believe that it is either appropriate or consistent with the ADA to defer to local laws that prohibit certain breeds of dogs based on local concerns that these breeds may have a history of unprovoked aggression or attacks. Such deference would have the effect of limiting the rights of persons with disabilities under the ADA who use certain service animals based on where they live rather than on whether the use of a particular animal poses a direct threat to the health and safety of others.
"Breed restrictions differ significantly from jurisdiction to jurisdiction. Some jurisdictions have no breed restrictions. Others have restrictions that, while well-meaning, have the unintended effect of screening out the very breeds of dogs that have successfully served as service animals for decades without a history of the type of unprovoked aggression or attacks that would pose a direct threat, e.g., German Shepherds. Other jurisdictions prohibit animals over a certain weight, thereby restricting breeds without invoking an express breed ban.
"In addition, deference to breed restrictions contained in local laws would have the unacceptable consequence of restricting travel by an individual with a disability who uses a breed that is acceptable and poses no safety hazards in the individual´s home jurisdiction but is nonetheless banned by other jurisdictions. State and local government entities have the ability to determine, on a case-by-case basis, whether a particular service animal can be excluded based on that particular animal´s actual behavior or history-not based on fears or generalizations about how an animal or breed might behave. This ability to exclude an animal whose behavior or history evidences a direct threat is sufficient to protect health and safety.
