Canine Cognitive Dysfunction Syndrome is a progressive neurological condition affecting senior dogs that causes significant welfare decline — yet it is dramatically underdiagnosed and undertreated.
Canine CDS is a welfare problem hiding in plain sight: millions of dogs are experiencing confusion, anxiety, disrupted sleep, and loss of previously learned behaviors without receiving diagnosis or treatment because their owners and sometimes their veterinarians interpret these signs as inevitable aging rather than a manageable medical condition. The welfare implications are substantial — a dog that is disoriented, unable to sleep, unable to recognize familiar family members, or experiencing anxiety in a previously comfortable home environment is experiencing significant subjective distress. CDS cannot be cured, but its progression can be slowed and its symptoms managed, allowing affected dogs a significantly better quality of life than without treatment. The most important initial intervention is accurate diagnosis: a veterinary assessment that distinguishes CDS from other conditions causing similar signs (pain, sensory loss, metabolic disease) and implements an appropriate treatment plan combining pharmaceutical, nutritional, and environmental approaches.
