Sealyham Terrier

Standing less than 11 inches at the shoulder and weighing about 24 pounds, Sealyham Terriers are tweeners—not quite big enough to be considered medium-sized dogs, yet among the strongest and most substantial of what we think of as small dogs. A typical Sealyham Terrier is like an NFL running back: powerful, well-muscled, built low to ground, and moving easily with long, determined strides. The weatherproof coat is predominantly white, and a long, broad head is furnished with the lavish facial hair so emblematic of Britain’s terriers.
