Health Considerations for Jack Russell Terriers

Their high activity level increases the importance of joint monitoring and injury prevention. Regular eye exams and maintaining a healthy weight are key components of long-term care.

Special note: The Jack Russell is an official breed in the Royal Kennel Club (RKC), but is not an official breed in the American Kennel Club (AKC) or Canadian Kennel Club (CKC). A subset of Jack Russell breeders sought AKC recognition, so that breed type was included in the AKC in 1997 as Jack Russel Terrier, but renamed the Parson Russell terrier in 2003. Russell Terriers are another distinct subset recognized more recently by the AKC and CKC, but not the RKC.
