English Mastiff and St Bernard Mix: A Comprehensive Guide

The English Mastiff and St Bernard mix is a giant of a dog, with adults weighing up to 230 pounds.

This massive size is due to the combination of the English Mastiff's massive build and the St Bernard's sturdy frame.

English Mastiff and St Bernard mixes are often referred to as "gentle giants" because of their calm and gentle nature, which makes them a great addition to families with children.

However, they do require regular exercise to stay healthy and happy, so be prepared for daily walks and playtime.

Their short coats require minimal grooming, but they do shed heavily, so be prepared for regular brushing and vacuuming.

The Saint Bermastiff is a gentle giant, but they do require regular grooming to stay clean and healthy. Regular brushing is a must, especially for those with long coats.

Daily brushing will help prevent matting, while shorter coats can get by with a quick brush once a week. If your Saint Bermastiff inherits the English Mastiff's coat, be prepared for more frequent baths to keep them smelling fresh.

Expect moderate shedding from your Saint Bermastiff, even if they don't inherit the St. Bernard's heavy shedding trait. Cleaning their ears regularly is crucial to prevent infections, and don't forget to trim their nails to prevent painful breaking and cracking.

Remember, neither parent breed is hypoallergenic, so this might not be the best choice for homes with allergy sufferers.

The Saint Bermastiff needs a well-balanced diet every day, with a lot of food to satisfy their huge appetite.

You'll want to feed your Saint Bermastiff about 4-6 cups of food every day, depending on their size and activity levels.

It's essential to choose a high-protein, low-fat food to keep your Saint Bermastiff healthy and happy.

As a giant breed, your Saint Bermastiff needs a diet made specifically for their size, with around 1.5% calcium, 22% high-quality protein, and 8% fat on a dry matter basis.

Feeding your Saint Bermastiff puppy a diet too high in fat can make them grow faster than their bones can accommodate, potentially resulting in skeletal abnormalities.

As your Saint Bermastiff grows, you'll want to switch to a diet that focuses on high-quality animal protein sources to maintain muscle tone, vitamins and minerals to support joints and cartilage, and less fat to keep an ideal body weight for less joint stress.

It's best to consult with your veterinarian about what to feed your Saint Bermastiff, how much, and how often, especially when bringing a new pup into your home.

To avoid gastric torsion or bloat, feed your Saint Bermastiff smaller meals multiple times a day rather than one large meal, and watch that they don’t drink too much water afterward.

Exercise is a crucial part of your Saint Bermastiff's daily routine. They don't require a lot of activity, but they still need physical activity to stay healthy.

Taking your dog for a brisk walk two times a day should be enough for some Saint Bermastiffs, but others may be more active and need more walking. You should keep your dog in good form because they can gain weight quickly if inactive.

Your Saint Bermastiff will need around 60 to 90 minutes of exercise daily, but avoid activities that require them to jump or run too much, as this can put stress on their ligaments and joints.

It's essential to monitor your dog's exercise levels, especially as a puppy. Avoid activities that involve excessive running and jumping, as this can cause strain and unnecessary problems later in life.

Grooming your Saint Bermastiff will depend on the coat texture they inherit from their parent breeds. Regular brushing is a must to keep their coat looking fresh, especially for those with a St. Bernard coat.

Daily brushing is needed to prevent matting in dogs with long coats. A simple pet grooming glove can work wonders for shorter coats, requiring only a weekly brush.

Expect moderate shedding from your Saint Bermastiff, even if they don't inherit the heavy shedding trait from the St. Bernard parent. This means regular vacuuming and tidying up loose hair.

Both parent breeds are prone to ear infections, so it's essential to clean their ears regularly. This will help prevent infections and keep your dog's ears healthy.

Trimming your Saint Bermastiff's nails regularly is crucial to prevent painful breaking and cracking. Keep their nails short to avoid any discomfort.

Don't forget to consult your vet about the best method for keeping your dog's teeth clean and in good condition. This is especially important for mastiffs with heavy jowls that can lead to a lot of drool.
