Summary
About Mastiff
The Mastiff is a giant, heavily built guardian dog, calm and dignified yet deeply devoted to its family. It is watchful rather than aggressive, needs gentle, consistent training, moderate exercise, and space. Its short coat is easy to maintain, but drool, health care, and costs are significant.
About Cavalier King Charles Spaniel
Small, gentle spaniel (5.4–8 kg) with a silky medium coat in Blenheim, Tricolour, Black and Tan, or Ruby. Affectionate, people oriented, and good with children and other pets. Needs regular grooming, moderate exercise, and dislikes long periods alone.
