Goldleaf Mastiffs

Goldleaf Mastiffs are mastiffs based in Sparta, TN, White County and the Cumberland Plateau near Cookeville. They adhere to health screening protocols for hips, elbows, heart, and eyes as recommended by the American Kennel Club and the Mastiff Club of America breeding guidelines.

Jann and Mark Lanz bring more than twenty years of combined experience caring for and training mastiffs on their rural, 15-acre property. Puppies are born indoors and raised alongside household life, enjoying daily social interaction, supervised outdoor play, and exposure to children and local farm activities. The Lanz family has maintained this breeder name for multiple generations, emphasizing sound temperament and structural integrity in each litter.

Recent owners note how smoothly Goldleaf pups adapt to family routines and often comment on their gentle, confident nature. Each puppy completes an early enrichment program and veterinary health checks before joining its new home.
