Audiometric Study Reveals Patternsof Age-Related Hearing Loss in Dogs and Cats

This study investigates the prevalence, progression, and characteristics of age-related hearing loss (ARHL) in domestic dogs and cats. Given the importance of auditory communication in these species, understanding ARHL’s impact is crucial for enhancing animal welfare and owner-pet interactions. Presbycusis, or age-related hearing loss, is a prevalent issue in dogs, usually beginning to impact them when they are between 8 to 10 years old. Initially, this condition manifests as a reduced capacity to hear sounds at mid to high frequencies, which can progressively worsen to total hearing loss. ARHL in cats generally begin to show signs around 8 to 12 years old as part of their aging process. Our study examines the behavioural adaptations that accompany this sensory decline, such as increased reliance on other senses and altered responsiveness, often misconstrued as an enhancement in hearing. Through comprehensive testing, this research aims to delineate the patterns of ARHL in these animals, highlighting the importance of early detection and management. The findings are intended to enhance the understanding of ARHL in pets, thereby aiding in the improvement of care strategies for senior dogs and cats experiencing this natural age-related change.

Purpose of Study: Age-related hearing loss in dogs and cats is an important area of study for several reasons:

• Animal Welfare: As pets age, hearing loss can significantly impact their quality of life. It can lead to confusion, anxiety, and changes in behaviour, as these animals rely heavily on their auditory senses for communication and environmental awareness. Understanding and addressing hearing loss can help in providing better care for ageing pets.

• Owner-Pet Relationship: Hearing loss in pets can affect their interaction with their owners. Pets with diminished hearing may not respond to verbal commands or react to their owners’ presence, which can be distressing for both the pet and the owner. By understanding the progression and impact of hearing loss, owners can adapt their communication methods to maintain a strong bond with their pets.

• Veterinary Care and Management: Knowledge about age-related hearing loss aids veterinarians in diagnosing and managing this condition more effectively. This can include providing guidance to pet owners on how to care for a pet with hearing loss and exploring potential treatments or interventions to slow down the progression of hearing loss. • Insight into Human Hearing Loss: Studying age-related hearing loss in animals can offer insights into similar conditions in humans. Dogs and cats have a relatively shorter lifespan, allowing for quicker observation of the progression of hearing loss. This can contribute valuable data to the broader field of auditory health research.
