The best pet for an elderly person with dementia depends on various factors, including the individual’s preferences, living situation, and level of cognitive function. In general, low-maintenance pets that provide companionship and emotional support can be beneficial. Small dogs or cats that are calm, gentle, and well-trained may be suitable options. Additionally, smaller animals like birds or fish can also offer companionship without requiring as much care. Ultimately, the best pet choice will depend on the individual’s specific needs and abilities, as well as their ability to care for and interact with the pet safely.
