Dog Walking Can Be Hazardous to Cutaneous Health

Author and Disclosure Information

Dog walking has been widely promoted by the medical profession for its potential health benefits, especially among older individuals. However, this activity has a less well-recognized risk for notable cutaneous, osseous, and even neurologic trauma. We chronicle 5 cases of dog walking gone awry, leading to minor to massive cutaneous trauma, as a precaution for providers who heartily endorse this seemingly benign pastime.

Practice Points

  • Dog walking is a good source of exercise but can lead to serious skin/soft tissue injury.
  • When evaluating cutaneous trauma related to dog walking, remember to consider the possibility of an underlying bone fracture.
  • Cutaneous trauma may overlay serious internal injury, such as epidural or subdural hematoma.

Studies have recommended dog walking as an activity designed to improve the overall health of older adults.1,2 Benefits purportedly associated with dog walking include lower body mass index, fewer chronic diseases, reduction in the number of physician visits, and decreased limitations of activities of daily living.2 The Arthritis Foundation even recommends dog walking to relieve arthritis symptoms.3 Of course, dogs also provide comfort in companionship, and dog walking can be an enjoyable way for a pet and owner to spend time together.

However, this seemingly benign activity poses a notable and perhaps grossly underrecognized risk for injury in older adults. The annual number of patients 65 years and older who presented to US emergency departments (EDs) for fractures directly associated with walking leashed dogs more than doubled from 2004 to 2017.4 Interestingly, this dramatic increase parallels a nationwide trend in dog ownership demographics. Between 2006 and 2016, the median age of dog owners in the United States rose from 46 to 49 years.5

These trends raise concern for more than just the health of older Americans’ bones. Intuitively, a dog- walking accident that results in a bone fracture will likely also lead to some degree of skin trauma. Older adults have thin fragile skin due to flattening of the dermoepidermal junction and disintegration or degeneration of dermal collagen and elastin.6 This loss of connective tissue as well as subcutaneous tissue in some body areas facilitates shearing injury; concurrently, weakened perivascular support increases the risk for vascular injury and bruising.7 Therefore, when an older person falls while walking a dog, trauma can easily damage delicate aged skin.

Older adults are particularly susceptible to falls, the leading cause of fatal and nonfatal injuries in this age group.8 There are multiple risk factors for falls, including polypharmacy, impaired balance and gait, visual impairments, and cognitive decline, among others.9

Also, many older adults with atrial fibrillation or venous thromboembolism take an anticoagulant drug to prevent stroke. The use of anticoagulants is associated with an increased risk for bleeding, ranging from minor cutaneous bleeding to fatal intracranial hemorrhage.10

A predisposition to falling and bleeding can be hazardous for a dog owner whose excited pet suddenly jumps, runs, or scratches. The use of a leash, mandatory in many urban jurisdictions, tethers the human to the dog, which expedites a fall associated with any sudden, forceful forward or lateral movement by the dog. The following case reports describe a variety of cutaneous injuries experienced by older adults while dog walking.

Case Reports

Patient 1
A 79-year-old woman was quietly walking her dog when the dog spotted a squirrel climbing a tree. The dog became excited, turned to the owner, and jumped on her, which caused the dog’s claws to dig into the owner’s fragile forearm skin, creating several superficial but painful abrasions and lacerations (Figure 1). These injuries healed well with conservative therapy including application of an occlusive ointment.
