Fort Knox Safety officials are warning dog owners to know which breeds are acceptable on post before they move here or purchase a new dog.Though the list of prohibited dog breeds is not long, it comes from the highest levels of the Army with the intention of safeguarding lives."This policy provides for the safety and welfare of all individuals on Army installations," reads Army Policy -- Domestic Animals on Army Installation.The policy also lists the following prohibited breeds: pit bulls like American Staffordshire bull terriers and English Staffordshire bull terriers, Rottweilers, Doberman pinschers, chows and wolf hybrids. Knox Hills adds dog breeds: Press Canario, Cane Corso and Neapolitan Mastiffs.Brian Wood, a safety specialist with the Fort Knox Safety Office, said installation residents should remember the policy and consider different breeds when looking for the perfect dog."It is everyone's responsibility to adhere to Army policy regarding animals who live and work on the installation," Wood said. "I recommend that potential pet owners really conduct their research prior to purchasing or adopting any animal."However, some residents may on occasion find a dog that's on the prohibited list because Knox Hills must adhere to Kentucky's Fair Housing Rules as a property manager in Kentucky.One rule is the Americans with Disabilities Act, which permits residents to have service animals and companion animals. The ADA has determined that these animals are necessary for the quality of life for the owners, so the animals do not fall under 'pet' policies for breed restrictions and limits.Army policy also states ultimate discretion for barring any pet breeds, including service animals, resides with the garrison commander.Regardless of the breed, Wood said all pet owners must maintain control of their pets at all times while in a fenced in area or on a leash."[This] makes the community safer for others who are enjoying the outdoors, visiting with neighbors," he said, "or playing on the community playground."
