The Bullsky Mastiff is a striking mixed breed, born from a Siberian Husky and a Bullmastiff. Most Bullsky Mastiffs are about the same size as their Bullmastiff parents, and they sport cute short muzzles that owners can’t seem to resist kissing. Their broad heads make these dogs look powerful, which they are in every way.

This mixed breed’s eyes tend to take after their Siberian Husky parent, but their bodies tend to take on the Bullmastiff physique. These dogs love to run and play, but they won’t pass up an opportunity to snuggle on the couch every now and then. Their thick coats won’t allow them to spend too much time in the sun without rest and lots of water between activities.

This hybrid dog is fun-loving and loyal, but it’s also highly active and can be quite stubborn. Therefore, those who don’t have much experience being dog parents may find the Bullsky Mastiff tough to handle. But with some training and commitment, this breed makes a wonderful family dog that kids and adults are sure to quickly bond with.

Things to Know When Owning a Bullsky Mastiff:

Just because Bullsky Mastiffs are cute and lovable doesn’t mean that everyone should own one. There are a variety of important things to know before deciding whether to become an owner of this interesting hybrid breed. Following is the important stuff every prospective owner should understand.

Food & Diet Requirements 🦴

Bullsky Mastiffs can eat up to 3 or 4 cups of dry food a day depending on their general activity level. These dogs don’t always enjoy scarfing down a whole bowl of food at one time. So, owners may notice that they need to leave the food bowl out all day long, while others find that multiple smaller meals throughout the day work well.

Due to the high activity of this breed, it’s a good idea to stick with high-protein food options that don’t include fillers such as corn. But grains are an important part of the Bullsky Mastiff’s diet, so their food should include high-quality options such as sweet potatoes, quinoa, and rice. Vegetables like carrots, beets, and kale are healthy additions to look for when reading the ingredients list.

Exercise 🐕

This is the type of dog breed that needs to get out and exercise daily. Long walks are a must several times a week. Some Bullsky Mastiffs enjoy taking two walks a day, especially if they don’t have a large yard to play in. This mixed breed also needs stimulation when spending time indoors to keep their minds busy and strong. Puzzle toys and hide-and-seek games are always fun options that both the human and the dog can enjoy together.

Training 🦮

Every Bullsky Mastiff should participate in obedience training as soon as possible after being adopted and going home for the first time. Obedience training will teach this breed all they need to know to become a patient, focused, and loving pet. This breed can also learn to become an excellent guard for the home if trained properly.

Any professional guard dog trainer can teach humans and their pet Bullmastiff & Siberian Husky mix the basics at home. Activities such as sledding and completing agility courses will provide some extra training that helps to keep these dogs fit and healthy well into their old age.

Grooming ✂️

Grooming requirements for this hybrid dog include a thorough brushing two or three times a week and a quick cleaning of the wrinkles that frame their face. Bullsky Mastiffs tend to groom themselves regularly, so they don’t typically need baths unless they get dirty while on a hike or when rolling in mud. The thick coats of these dogs make a great home for fleas, so regular treatments (especially during the summer months) are usually needed to keep flea infestations from developing.

Health and Conditions ❤️

Most Bullsky Mastiffs grow up to be healthy, happy dogs with little to no health issues. But there are a small handful of problems that owners of this spectacular breed should be aware of.

Minor Conditions
  • None to note
Serious Conditions
  • Cardiomyopathy
  • Hip dysplasia

Male vs. Female

Like with most dog breeds, male Bullsky Mastiffs are usually a little bigger than their female counterparts. Female Bullmastiff & Siberian Husky mixes are just as independent as males, and the boys are just as affectionate as the girls. Many owners report that males seem to be easier to potty train than females. But overall, both genders have loving, loyal qualities that owners should appreciate just the same.
