Exploring the Importance of Repeated Health Screening in Healthy Older Dogs

Area of Science:

• Veterinary Medicine
• Canine Health
• Aging Animal Studies

Background:

• The clinical significance of serial health screenings in aging dogs is not well-established.
• Factors influencing survival in older dogs require further investigation.

Purpose of the Study:

• To evaluate the health status of apparently healthy senior and geriatric dogs through comprehensive screening.
• To identify common diseases emerging within two years in initially healthy dogs.
• To assess the prognostic value of baseline clinicopathological variables for mortality in healthy older dogs.

Main Methods:

• A prospective, longitudinal study involving 122 apparently healthy senior and geriatric dogs.
• Annual history, physical examination, blood tests, and urinalysis over a two-year period.
• Baseline assessment of clinicopathological variables and physical examination findings.

Main Results:

• Twenty percent of dogs were diagnosed with at least one disease at baseline, leaving 98 for follow-up.
• Common emerging conditions included neoplasia (12%), azotemic chronic kidney disease (CKD, 8%), neurologic disease (11%), and orthopedic disorders (5%).
• Malignant neoplasia was detected in 47% of affected dogs via physical examination. Only age group predicted survival, with geriatric dogs having higher mortality.

Conclusions:

• Regular health screenings are crucial for identifying previously unrecognized diseases in older dogs.
• Repeated screening for CKD, neurologic, and orthopedic conditions, along with rectal palpation, is particularly relevant.
• Age is a significant factor in survival, with geriatric dogs exhibiting increased mortality risk.
