Maremma

Maremma’s are a breed of livestock guardian dogs known for their strong protective instincts and tendency to bark. 
Maremma’s, may bark to mark their territory. This behaviour is more common in dogs that live in a specific area and need to establish boundaries. Barking can be a way for them to communicate their presence and assert their territory. They have a deep, loud bark that can be heard from a distance. t's worth noting that each individual dog is unique, and their barking behaviour can vary. Some Maremma’s may be naturally more vocal than others.

Bark Control Solution
Dogmaster Trainers recommends a static bark control collar with manual settings for any Maremma. Being highly intelligent, over time they can understand how an auto rise output works, making this style of collar less effective. Collars with a manual adjustment allows you to go straight to the level that the dog responds to and keep it there.
Choose an e-collar from a reputable manufacturer that offers multiple levels of stimulation and adjustable settings. This allows you to use the minimum level required to get your dog's attention without causing undue discomfort or distress.Recommend Anti Bark collars: Dogtra YS600

Remote Trainers
Dog training collars often come with a remote control, allowing you to deliver commands or corrections from a distance. This can be helpful for reinforcing obedience commands or discouraging unwanted behaviours such as excessive barking or digging.
