Summary
About Bullmastiff
Large, powerful guardian originally bred to catch poachers, the Bullmastiff is calm, confident and deeply loyal, often bonding closely with one person. It has a short, low‑maintenance coat, needs space, consistent early training and socialisation to guide its natural protectiveness.
About Biewer Terrier
The Biewer Terrier is a small, tri-colored toy companion dog with a long, silky, low-shedding coat that needs frequent grooming. Cheerful, playful, and people-oriented, it suits apartment living, needs moderate exercise, gentle training, and can live into its mid teens with good care.
