Is the Mastiff Inglés a good match for you?
Indicative rating from 1 (low) to 5 (high).
💶 Estimated cost of ownership
120-200 €/month
Giant-breed food 60-100 €; public liability and health insurance 25-45 €; parasite control and prevention 15-25 €; vaccines and check-ups spread out 20-30 €. The large size drives up the cost of medication, anaesthetics and surgery.
History and origin
An ancient English breed, descended from Roman mastiffs. An estate guardian for centuries. Almost extinct in WWII; since recovered.
Recognised by the FCI within Group 2 (mastiffs). In the UK it appears on farms and estates as a guardian, as well as in homes with space. Adults living to 6-10 years: the short average lifespan is a consequence of the extreme size and calls for specific care.
Temperament and character
Calm, devoted, brave. Excellent with children. Reserved with strangers without aggression. Sociable. Needs daily mental stimulation — scent games, food-stuffed Kongs and short tricks channel its energy better than physical exercise alone. Responds best to positive reinforcement: physical punishment causes fear, anxiety and reactivity — coercive methods are NOT recommended by veterinary behaviourists. Sensitive to the family's mood: it senses tension and picks up on it.
Living together
Children: excellent. Other dogs: tolerant. Cats: good.
Life stages of the Mastiff Inglés
Each stage has its own care priorities. Life expectancy: 6-10 años.
Puppy
0-1 year
Slow, controlled growth with a giant-breed diet; gentle exercise to protect the developing joints.
Young
1-2 years
Radiographic screening for hip and elbow dysplasia; split meals to prevent gastric torsion.
Adult
2-5 years
Strict weight control; echocardiography for cardiomyopathy risk; eye examination (entropion).
Senior
5+ years
Management of osteoarthritis and mobility; cardiac check-ups and monitoring for bone tumours; comfort and orthopaedic beds.
Care
Exercise: 30-45 min/day split into at least 2 sessions. Calm walks + mental play.
Grooming: 2-3 times/week; intensive during the moults (spring and autumn).
Feeding: quality food appropriate to the life stage (puppy/adult/senior) and size. Weight control: obesity is the leading preventable cause of joint problems.
Veterinary care: annual check-up with preventive blood work from 5 years (7 years in giant breeds); twice a year from 8.
Moderate exercise (45 min/day), avoid jumping during growth. Weekly grooming. Cleaning of the skin folds. Padded bed. Weight control.
Care in detail
🍽️ Nutrition
Giant-breed-specific food throughout growth (up to 18-24 months) to slow development and protect the joints. Split the daily ration into 2-3 servings and avoid intense exercise straight after eating.
✂️ Grooming
Short, low-maintenance coat: weekly brushing. Daily cleaning of the facial folds and dewlap to prevent dermatitis and infections.
🎓 Training
Socialisation and basic obedience from puppyhood, while it is still manageable: an 80 kg adult must walk on a loose lead. Positive reinforcement; it is sensitive and does not tolerate harsh methods.
🏃 Exercise
Low needs: 2 calm walks a day totalling 30-45 minutes. Avoid jumping and stairs during growth and never exercise it in the heat.
Breed-specific health
Dysplasia. Bloat. Cardiomyopathy. Osteosarcoma. Cystinuria. Life expectancy 6-10 years (very short). Life expectancy 6-10 years with proper care. Pre-breeding testing is recommended at responsible kennels (dysplasia + cardiac + ophthalmology according to the breed's conditions). When adopting, ask the rescue for a vet report on the current state of health.
