At English Mastiff Haven, we are dedicated to the highest standards of care and ethical breeding for English Mastiffs. Our approach is rooted in compassion, responsibility, and a commitment to the long-term health and happiness of every dog we raise.

Breeder Transparency Statement:

“We are committed to long-term health of our breed. Our parent dogs undergo genetic screening, and we fully disclose all results, including carrier status. ‘Being a carrier’ means the dog carries one copy of a specific gene but is perfectly healthy and will never develop the condition. We use this data to ensure responsible pairings, only breeding carriers to clear mates to guarantee that no puppies are ever affected by the disease.”

Health & Wellness:

  • All of our parent dogs are AKC registered, And genetic tested.

  • We prioritize regular veterinary care, and vaccinations for both adults and puppies.

  • Our dogs enjoy spacious grounds for exercise and a temperature-regulated playhouse for comfort, supporting their physical and emotional well-being.

Health Guarantee:

  • Puppies receive thorough veterinary examinations and are up-to-date on vaccinations and deworming before joining their new families.

  • We provide documentation of health checks and vaccination records for your peace of mind.

  • If a health issue covered by our guarantee arises within the specified period, we will work with you to ensure the best outcome for your puppy, including support and guidance on next steps.

Socialization & Family Life:

  • Our English Mastiffs are raised in a loving, family-centered environment, sharing our daily lives and routines.

  • Puppies are introduced early to family interactions helping them develop into friendly, well-adjusted companions.

  • We believe that early socialization is key to nurturing gentle, loyal, and protective family members.

Ethical Practices:

  • We never compromise on the quality of life for our dogs.

  • Each puppy receives individual attention, affection, and care from birth until they join their new families.

  • We are transparent about our breeding practices and welcome questions from prospective owners.
