Appearance-wise, Lakeland Terriers resemble the Welsh Terrier, although slightly smaller and both breeds bear a resemblance to their somewhat larger cousin, the Airedale Terrier. Ideally, they must weigh 15 to 17 pounds and grow to a height of 33 to 38 centimetres at the shoulders (withers). Its head is rectangular-shaped, eyes are dark or hazel with intense and an impish expression, ears are V-shaped that fold over, and tail docked and carried up. It has long legs that allow it to run at incredible speeds and its slim body gives it easy access to small passageways to capture prey. Its tail is generally docked (US) or left long (Europe).
The Lakeland Terrier has a coat that is thick and dense, comprising of a profuse, wiry outer coat and soft undercoat. It comes in many colours including black, blue, liver, wheaten, and red. Some will have a tan or red grizzle saddle that covers their neck, back, sides and tails, which make them appear blue and tan, black and tan, liver and tan, red grizzle and grizzle and tan. Shedding in the Lakeland Terrier is minimal, and it is reduced even further when the coat is stripped correctly. Stripping is not necessary if the Lakelands will not be shown. Weekly brushing of the coat will help keep the coat clean and excess oil well-distributed. Also, Lakelands only need to be bathed as needed.
Check the ears once a week for signs of wax build-up, irritation or infection. Clean the ears with a cotton ball moist with a veterinarian-approved solution. Teeth should be brushed weekly (even daily) to prevent tartar build-up and promote gum health. Trim nails to avoid overgrowth, cracking and splitting that may become painful for the dog.
