  • Just like any other big dog, they are prone to hip and elbow dysplasia
  • This breed is also prone to a form of skin infection called lip-fold pyoderma. The folds of skin along the lower jaw are usually moist. Due to that, bacteria and yeast can develop there and the smelly area becomes uncomfortable for your dog.
  • Osteosarcoma – a type of bone cancer is also evident in these dogs which affects around 8 to 10 thousand Mastiffs in the USA.

Things to watch-out before deciding to own a English Mastiff

There are a few cautions that you need to know before deciding to adopt a Mastiff

  • They may not be very great with other dogs or even your own pets at home especially if they are smaller in size as the sheer size of these dogs will scare them and can lead to aggression
  • These dogs can be on the expensive side including its initial purchase and the later care.
  • They require a specific kind of a diet to keep up with their huge bulk which can be steep on the budget for some families
  • They can be really stubborn at times during trainings or other activities making it difficult for them to teach obedience
  • They shed a lot. Although not hypoallergenic, the hair lying around your house can be a task all the time
  • They also happen to drool more than usual. So be ready to carry a napkin / towel around often
  • Due to their size, supervision may be needed around young children
  • With excitement you might want to lift your pup at several occasions but their huge bulk can come at an expense of your back. So make sure you ‘lift’ before you lift.
