In the DISHAAL acronym for CCDS, what does the 'L' represent?

• A. Learning and memory difficulties
• B. Language decline
• C. Latent infections
• D. Lethargy

Answer: (A)

In the DISHAAL acronym used for Canine Cognitive Dysfunction Syndrome, the L stands for Learning and memory difficulties. This reflects the cognitive core of the condition—dogs having trouble learning new tasks, recalling familiar routines, or recognizing previously known cues. It’s a sign of the brain’s declining ability to encode and retrieve information, which underpins the other observed signs like disorientation, changes in sleep-wake patterns, house soiling, and altered activity or anxiety.

Language decline isn’t a typical sign in dogs, as they don’t communicate the same way humans do. Latent infections don’t fit cognitive signs, and lethargy is a broad symptom that can accompany many conditions but doesn’t specifically capture the memory and learning challenges highlighted by this acronym.
