About the Border Terrier

The Border Terrier hails from the border country between England and Scotland, where it was bred to bolt foxes from their dens while keeping pace with mounted hunters and their hounds. One of the smaller terrier breeds, it stands 12–15 inches tall and weighs 11.5–15.5 pounds, with a compact, narrow body designed to squeeze into fox burrows. Their distinctive otter-shaped head and wiry, weather-resistant double coat — which comes in red, grizzle-and-tan, blue-and-tan, or wheaten — give them a charmingly scruffy appearance.

Temperament & Personality

Border Terriers are affectionate, plucky, and adaptable — they have all the tenacity of a terrier but with a softer, more biddable temperament that makes them excellent family companions. They are good with children and generally get along better with other dogs than many terrier breeds. However, their strong prey drive means they cannot be trusted around small animals like hamsters, rabbits, or guinea pigs.

Pros

  • Adaptable to both country and city living — they adjust well to apartments with adequate exercise
  • More trainable and less confrontational than many terrier breeds
  • Low-shedding wiry coat that requires only periodic hand-stripping
  • Robust and healthy with a long lifespan of 12–15 years

Cons

  • Strong prey drive — they will chase squirrels, cats, and small animals relentlessly
  • Can be expert diggers and escape artists if left in a yard unsupervised
  • Hand-stripping the coat is time-consuming, and clipping changes the coat texture permanently
  • Prone to canine epileptoid cramping syndrome (Spike's disease) and heart defects

These scrappy, lovable terriers make wonderful companions — discover adoptable Border Terriers on Puplister.

About the Cavalier King Charles Spaniel

The Cavalier King Charles Spaniel traces its heritage to the toy spaniels beloved by English royalty — King Charles II was so devoted to the breed that it bears his name. Standing 12–13 inches tall and weighing 13–18 pounds, the Cavalier is a graceful, well-balanced toy spaniel with large, round, dark eyes and a gentle, melting expression. Their silky, medium-length coat comes in four distinct color patterns — Blenheim (chestnut and white), tricolor, black-and-tan, and ruby — and features elegant feathering on the ears, chest, legs, and tail.

Temperament & Personality

Cavaliers are gentle, affectionate, and remarkably adaptable — they are equally happy curled up on a lap or joining their owner for a brisk walk in the park. They are one of the most universally friendly breeds, greeting strangers, children, other dogs, and even cats with a wagging tail and a joyful expression. Their sweet, eager-to-please nature makes them excellent therapy dogs and wonderful companions for seniors, families, and first-time dog owners alike.

Pros

  • Exceptionally gentle and affectionate — one of the best lap dogs and therapy dogs available
  • Highly adaptable to various lifestyles — equally content in apartments or country homes
  • Friendly with everyone — strangers, children, other dogs, and cats
  • Easy to train with positive reinforcement due to their eager-to-please temperament

Cons

  • Extremely prone to mitral valve disease — nearly all Cavaliers develop heart murmurs by age 10
  • Susceptible to syringomyelia, a painful neurological condition caused by skull malformation
  • Cannot be trusted off-leash due to spaniel hunting instincts and lack of street awareness
  • Prone to separation anxiety — they do not cope well being left alone for extended periods

Few breeds match the Cavalier's gentle, loving spirit — find adoptable Cavalier King Charles Spaniels on Puplister and experience their magic firsthand.
