Along with being a warmhearted companion, Norfolk Terriers are also one of the smallest working terriers, standing no more than 10 inches at the shoulder and weighing just 11—12 pounds. The Norfolk Terrier is an affectionate and spunky little dog that makes a wonderful pet.
They have perky personalities and love adventure but will settle down for cuddles. Most individuals are very patient with children, though kids should always be taught how to interact with small dogs. They have moderate grooming needs. The average Norfolk Terrier lifespan is 12—16 years— longer than the average dog. They are generally hardy, healthy dogs , but Norfolks are predisposed to a few medical conditions that are more common in the breed.
One of the most serious conditions that can occur in Norfolk Terriers is a form of degenerative heart disease called myxomatous mitral valve disease MMVD.
In this condition, the heart allows blood to flow back in the wrong direction. This can create a heart murmur , heard as a whooshing sound when the heart is listened to with a stethoscope.
Over time, this abnormal blood flow often causes enlargement of the heart and may lead to congestive heart failure. Some dogs with MMVD never develop severe disease, while others may need intensive care. A physical exam by a veterinarian should be performed at least once a year. If they hear a heart murmur, your vet may recommend chest X-rays to evaluate the size of the heart and the vessels around it.
