Things to Know When Owning a Spanish Mastiff

Here’s what you should know when owning a Spanish Mastiff.

Food & Diet Requirements 🦴

A healthy diet is essential for this breed. Their diet should contain all the nutrients they need to be healthy, along with a balance of protein, carbohydrates, and fats. Spanish Mastiffs will benefit from food for large breeds.

You can either feed them a kibble, wet, raw, or freeze-dried diet, depending on what works best for their lifestyle and overall health. It's best to speak with a veterinarian or certified canine nutritionist about which foods are suitable for your dog.

Keep in mind that Spanish Mastiffs shouldn’t have too many treats or table scraps, to avoid excessive weight gain. Obesity can put strain on their joints and negatively affect their mobility.

Exercise 🐕

Spanish Mastiffs do not have high energy needs, but they still require daily exercise for their overall well-being. These dogs need both physical and mental stimulation during exercise. This includes going for a walk or run, along with interactive toys or activities to prevent boredom. Try to exercise your Spanish Mastiff for at least 45 minutes to an hour every day.

You could also exercise them throughout the day. You could take them for a morning walk and then another walk later in the day. You can let them play in a secure yard or dog park in the afternoon and give them toys to play with in the evening.

Training 🎾

The Spanish Mastiff’s high intelligence and eagerness to work make them relatively easy to train with the proper methods. However, this breed can be stubborn at times and resistant to training methods that don’t engage their interest. Early socialization and training should begin once a Spanish Mastiff is at least 8 weeks old.

You don’t want to put off training these dogs and wait until they are already adults. Spanish Mastiffs don’t easily break habits they have grown up doing before they began training. High-value rewards will be your best friend when training your dog.

Grooming ✂️

Spanish Mastiffs have thick coats with moderate grooming requirements. They also shed a moderate amount of fur throughout the day, so grooming can help maintain the amount of shed hair in your home.

Their hair is short, so brushing them is a breeze. Bristle brushes are great. You can also use a de-shedding rake for more effective shedding control. Spanish Mastiffs don’t need to be bathed too often, usually only when their coat becomes dirty. A cleansing shampoo followed by a non-greasy conditioner will help keep their coat looking fresh and manageable.

Spanish Mastiffs also need their nails trimmed and ears cleaned once or twice a month.

Health and Conditions 🏥

Although the Spanish Mastiff is a relatively healthy breed, they can still be affected by several health conditions.

Male vs. Female

Neutering your Spanish Mastiff may help prevent unwanted hormonal behaviors while preventing accidental litters or certain reproductive problems.
