As a larger working breed, Great Pyrenees stand out because of their adorably fluffy coat and determined personalities. But, their built-in temperament requires special training to curb their tendency to bark.

"These dogs were bred to keep predators away from farm animals, especially when the owners are not nearby," says Grottini. "They often watch a herd of livestock during the night hours to keep livestock safe from predators like wolves and coyotes. Their barking will continue until the predator moves away or is taken care of by the owner."

According to Bassett, guarding breeds that are not properly socialized from a young age can easily become overwhelmed by new and unfamiliar stimuli and may bark a lot as a result.

Known for their intelligence and friendly disposition, Australian Shepherds are a popular family pet pick. However, their breed's history also means they can be vocal.

"Aussies are herding dogs at heart and use their bark to control and direct livestock," says Sara Ochoa, a veterinarian in Louisiana. "This instinctual behavior means they're also likely to use their voice to try to 'herd' humans or other pets at home."

For many pet owners, Chihuahuas are a perfect pocket-sized choice for companionship. But, according to Rice, they pack a surprisingly big bark.

"Despite their tiny size, Chihuahuas have a big personality and tend to bark as though they are much bigger than they are," he says. "These pint-sized pups are often quite vocal, using their barks to communicate their feelings and needs."

He warns that they may become habitual barkers without proper training. "Early socialization is important to avoid this," Rice suggests.

German Shepherds are often seen as the epitome of poise, security, and even temperament. But though they are renowned for their loyalty, intelligence, and protective nature, they can also be prone to making more noise than other breeds.

"While their barks serve as a warning to potential intruders, they can also bark out of boredom or anxiety if not provided with sufficient physical and mental stimulation," says Rice. "Fortunately, with consistent training and exercise, their barking can be managed effectively."

Rounding out the loud and proud small barkers is the Yorkshire Terrier.

"They are bold and aggressive, with a tendency to bark at unfamiliar sounds or perceived threats," says Rice.

"Early socialization and positive reinforcement training can help curb their barking tendencies and channel their energy into more constructive behaviors."
