Spanish Mastiffs need sufficient room for daily exercise, but they're not high-energy breeds. They require about an hour of exercise every day, which can include a long walk, swim, or playtime in the house or a fenced yard.

Their grooming requirements are fairly straightforward, but training and socialization should receive extra attention to ensure that the dog is friendly and well-mannered. Obedience training should be pursued when a Spanish Mastiff is young, so they grow into a well-mannered dog.

To prevent excess weight gain, be mindful of treats and other extra food. A Spanish Mastiff might benefit from a dog food that's formulated for large breeds, and it's typical to feed two measured meals per day to ensure that your dog is getting the correct amount.

Remember to discuss the type of food and the amount with your veterinarian to ensure you're feeding your Spanish Mastiff the best.

A joint supplement and an omega-3 fatty acid supplement (fish oil) may be recommended by your veterinarian to support your dog's joints, especially if your dog weighs over 140 pounds.

Talk to your veterinarian before giving any supplements to your dog.

To minimize the risk of bloat or GDV, feed your dog two or three smaller meals a day, instead of one large meal.

Avoid using elevated food bowls, and don't exercise your dog one hour before to one hour after a meal.

Here are some estimated daily calorie needs for Spanish mastiffs based on their activity level:

Remember to consult with your veterinarian to determine the correct portion size for your Spanish mastiff based on their ideal body weight, life stage, and health.

Grooming is an essential part of Spanish Mastiff care. The breed doesn't require a professional groomer, but regular brushing is necessary to prevent matting.

Weekly brushing with a pin brush and comb is recommended, especially during mild shedding periods. A deshedding rake should be used once or twice a week during heavy shedding seasons, which occur in the spring and fall.

The Spanish Mastiff sheds year-round, with heavier shedding in the spring and fall. This means you'll need to brush your dog more frequently during these seasons to minimize the amount of fur shed indoors.

You'll also need to clean your dog's ears occasionally and trim their nails as needed. Some working Spanish Mastiffs may wear down their nails in the field, but this isn't always the case.

Spanish Mastiffs are huge droolers, especially after exertion, eating, or drinking. If you let your dog in the house, consider keeping drool rags handy, preferably made of leather or faux leather, which are easier to clean and dry than cloth fabrics.

Here's a brief guide to Spanish Mastiff grooming:

Training a Spanish Mastiff requires patience and consistency. Positive-reinforcement training methods work best, making training sessions fun and varied.

Start training and socialization when your puppy is young, ideally in a puppy class. This will help teach basic commands and manners.

A Spanish Mastiff's size can make it challenging to manage if it hasn't been well-trained. Early socialization and training are crucial to prevent this.

Socialization is key to exposing your Spanish Mastiff to various people and other dogs from an early age. This will help your dog view strangers as non-threatening.

A Spanish Mastiff is not known to be anxious or fearful, but it will become alert when a stranger or unfamiliar animal is nearby.

Their bark is low-pitched and deep, and can be heard from a distance. They may bark to alert loved ones of a possible threat, even if it's just a delivery person.

Because of their independent nature, Spanish Mastiffs can be difficult to train. People with more experience training dogs are better equipped to train a Spanish Mastiff.

Obedience training classes should start when your dog is young, and positive reinforcement is essential. If needed, seek a professional dog trainer.

A Spanish Mastiff's loyalty and devotion to its family make it a wonderful protector of its home and family. Consistent and firm training is necessary to establish the dog's respect as a leader.

With proper training and socialization, a Spanish Mastiff can be an extremely loyal pet. Supervised exposure to unfamiliar dogs in puppyhood can help dampen aggression towards other dogs.
