Mastidoodle Breed History

The history and origin of the Mastidoodle still remains a mystery as the hybrid only likely emerged within the last 20 years. Nevertheless, the Mastidoodle is a hybrid currently recognized by the American Canine Hybrid Club and Dog Registry of America, both American dog breed clubs. It can be speculated that this hybrid originated from the Americas. The Mastiff parent breed we know today is believed to have descended from various ancient giant breed dogs such as the Tibetan Mastiff, Saint Bernard, Dogue de Bordeaux, and Rottweiler and emerged in England during the 15th century. However, the original Mastiff can be traced back over 2500 years ago to many places such as Asia and Egypt. These strong, breeds often served as guard dogs and protectors of their owners. The Standard Poodle is another ancient breed that was believed to have first emerged during the first century B.C. These ancient breeds have gone through much progression over the centuries and over time were crossed with breeds such as the Russian, Spanish, German and French water dogs along with various Asian dog breeds. The breed we know today is currently considered the National dog of France. They are easily one of the most intelligent dog breeds known and serve as guide and service dogs.

Mastidoodle Breed Maintenance

The Standard Poodle is considered one of the highest maintenance dog breeds when it comes to grooming. Most Mastidoodles tend to retain the wavy, thick,  dense coats of the Standard Poodle and so it is possible that they can be hypoallergenic and low shedders. But, don't expect grooming to be cheap or easy.  Your Mastidoodle will need to be groomed roughly every 6 to 12 weeks depending on where you live and the climate. During the summer months, some Mastidoodles may need to be groomed every 4 weeks in order keep them cool. 

In addition to grooming, Mastidoodles will need their teeth brushed weekly, nails trimmed every 6 weeks, and ears cleaned and checked for signs of infection.

Mastidoodle Temperament

Thinking of adopting a  Mastidoodle? Don't let their size fool you! These hybrids are considered "teddy-bears" as they are a well-tempered, loyal breed that is very well mannered despite its intimidating size. The Mastidoodle is a hybrid that gets along quite well with every family member. They do well in a family environment and make great cuddle bears for children or small pets. However, as these are big dogs it is important to never leave a child or small pet unattended as the Mastidoodle's playful behavior and size can knock them over or hurt them unintentionally. These hybrids actually make really great watchdogs! Their protective, courageous personality is a trait often observed in the parent breed, the Mastiff. The Mastidoodle will bark to warn their owners of a possible stranger near their home. The Mastidoodle should never be left home alone too long, as these breeds carry the Poodle gene; it is important to realise that boredom and lack of mental stimulation can lead to anxious or destructive behavior.

Mastidoodle Activity Requirements

The Standard Poodle is an active, agile, athletic breed, whereas the Mastiff is only a moderately active breed. Your Mastidoodle is likely to fall somewhere in the middle when it comes to its activity level. The Mastidoodle may enjoy activities such as tug-of-war, long walks, short runs and playtime at the dog parks. They are suited to all homes and lifestyles so long as they have plenty of space to play and rest. They may not be suited to small apartments due to lack of space.

This is actually a boerboel/std. poodle cross. First I've ever heard of. At 6 mos, he weighed 69 lb. Today, at 8 mos, he weighs 87 lb. and is 28" tall. As expected, we have an excellent guard dog. We'll see how he fares when the grizzlies wake up in a few weeks.

We love piper she is so amazing with our kids and very much a guardian. She won’t leave their side when they are sick, she sleeps in between their rooms frequently checking on them in the night . She is so gentle . She does bark a lot at anybody who comes near our home . She listens very well and loves to play and run but is very chill in our home .

Vouge is a over friendly gentle giant. Loves a bit of fuss but can get over excited. The only hard part of her training is her recall. If she she‚Äôs another dog she‚Äôs off like a rocket ūüöÄ. Vouge lives in the United Kingdom
