Miniature Pinscher (Min Pin)

Scottish Terrier
The terrier group of dogs are infamous for being vocal, so it comes as no surprise that the Scottish terrier made the list. The sturdy and independent Scottish terrier is known to be territorial and intensely loyal to its family and will sound off the alarms with intruders. Compact yet fearless, it will usually only bark if necessary.

Golden retrievers ranked at No. 1 for having the loudest bark in the world at 113 decibels, according to Guinness World Records. While playful with children, this dog is essentially a protector and its loud bark is effective whether hunting, serving in a search and rescue capacity, or as a loyal protector of its family. One of the most popular breeds in the U.S., the versatile golden retriever is widely loved for being an intelligent, gentle and devoted companion.

The second-loudest bark recorded was in 2009 from a German shepherd named Daz at 108 decibels, which is equally as loud as a power saw. Bred to serve as protectors and guardians, German shepherds work as military and police dogs, and as service dogs to assist the visually impaired. Devoted to keeping intruders away, this breed will swiftly alert others at the slightest sign of suspicious activity.

SAN ANTONIO — If you’ve wanted to adopt one of the TSA dogs that didn’t pass the explosives detection training or are retiring from service, there's some bad news.

The Transportation Security Administration, which runs a canine training center at Joint Base San Antonio-Lackland, is out of pups looking for homes.

“We currently don’t have any dogs for adoption, ” said TSA spokeswoman Carrie Harmon.

She said the earliest time a dog could be available would be late spring.

“Due to the overwhelming interest and the number of applications and inquiries already received, the program is not currently accepting new applications for future adoptions, ” said Harmon, citing a large waiting list already established for the adoption program.

The dogs are primarily raised in kennels, so they aren’t used to living in a household environment, which means a little extra training might be needed for the dogs. The dogs typically range in age from two to 10 years old.

Conventional explosives detection canine handlers go through training for 10 weeks, while passenger screening canine handlers undergo a 12-week training course.

Canine teams graduate from the TSA canine course after proving excellence in various venues inclusive of all transportation including airport, terminal, freight, cargo, baggage, vehicle, bus, ferry and rail, according to TSA.

Each canine team is tested to ensure they can recognize explosive odors, handlers can interpret a canine’s change in behavior, the handlers can conduct logical and systematic searches and the team can locate an explosive odor’s source.

The training facility at Joint Base San Antonio-Lackland is a $12 million Canine Training Center that includes 25, 000 square feet of space with seven classrooms, office space for 95 employees and a 100-seat auditorium.
