You know your senior dog has dementia, also called Canine Cognitive Dysfunction (CCD), by recognizing signs like Disorientation (getting lost in familiar places), Sleep changes (pacing at night, sleeping all day), House soiling (accidents indoors), Interaction changes (anxiety, irritability, or withdrawal), and Activity changes (staring at walls, less interest in walks). These signs often follow the DISHAA acronym: Disorientation, Interactions, Sleep-wake cycles, House-soiling, Activity levels, and Anxiety.

At what age can dogs get dementia?

Dementia, also known as canine cognitive dysfunction (CCD), is the deterioration of the brain seen in senior dogs, starting around age 9. Symptoms and signs include confusion, irritability, anxiety, changes in appetite, not wanting to play, house soiling, and compulsive behaviors, among others.

Dog dementia (Cognitive Dysfunction Syndrome - CDS) causes confusion, anxiety, sleep changes, and house-soiling, with behaviors like getting lost in familiar places, increased nighttime restlessness or vocalizing, accidents indoors, withdrawn or clingy behavior, and losing interest in activities, often summarized by the acronym DISHAA (Disorientation, Interaction changes, Sleep-wake cycles, House soiling, Altered activity, Anxiety). These changes stem from brain aging, but a vet visit is crucial to rule out other serious illnesses like tumors or infections that mimic dementia symptoms.
