Bullmastiff puppies for sale in Brentwood

10 Bullmastiff puppies for sale in Brentwood

Bullmastiffs are powerful looking dogs that are the result of crossing an Old English Mastiff with a Bulldog. Originally bred to help gamekeepers track down poachers, these large dogs have become popular companions not only here in the UK but elsewhere in the world. They are intelligent and alert characters that are easy to train, but they want to know why they are doing something, which is something to consider when training a Bullmastiff. They are known to be temperamental and quickly become loyal family members, always ready to protect the people they love and their property.

How much does a Bullmastiff cost?

The average cost of a purebred Bullmastiff puppy in the United Kingdom is approximately £674, though prices can vary based on factors such as pedigree, breeder reputation, and location.

Is Bullmastiff a good family dog?

Yes, Bullmastiffs are generally good family dogs. They are loyal, protective, and gentle with children, making them suitable for families. However, they require proper training and socialization from a young age.

What are the downsides of Bullmastiffs?

Bullmastiffs can be prone to health issues like hip dysplasia and certain cancers. They also tend to be somewhat stubborn and may require consistent training and socialization. Additionally, their large size means they need ample space and regular exercise.

Can a Bullmastiff be left alone?

Bullmastiffs can be left alone for short periods, but they thrive on companionship and may become anxious if left alone for too long. It's important to provide them with mental stimulation and gradually train them to be comfortable when alone. Extended isolation is not recommended for their well-being.

Do Bullmastiffs live long?

Bullmastiffs typically have a lifespan of around 7 to 9 years. While they are generally healthy, their large size can contribute to a shorter life compared to smaller breeds. Proper care and regular veterinary check-ups can help maximize their lifespan.
