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

• A. Interaction changes
• B. Inactivity
• C. Irritability
• D. Incontinence

Answer: (A)

Interaction changes. In canine cognitive dysfunction syndrome (CCDS), the I in the DISHAAL acronym marks shifts in how the dog socializes with people and other animals. As cognitive function declines, dogs often become less responsive to familiar handlers, show reduced interest in greeting or seeking attention, or interact differently during social play. Framing this as “interaction changes” captures a broad spectrum of social behavior alterations that are characteristic of CCDS, not just changes in mood or energy.

Why this stands out: social engagement is a key behavioral domain affected by cognitive decline, and noticing a change in interactions with owners or companions can be an early and important cue that CCDS is present, guiding further assessment and management.

Inactivity, irritability, and incontinence describe other concerns a clinician might assess, but they do not define the interaction-change domain identified by the I in this mnemonic.
