For some elderly dogs, memory loss can be a challenge. In fact, the aging canine brain can be very similar to a person’s affected by Alzheimer’s disease.

But when a geriatric dog forgets housetraining routines, doesn’t recognize family members, becomes confused or alters sleeping habits, the changes may just be chalked up to old age.

If you start to notice these changes in your dog, first schedule a veterinary exam to rule out systemic illness. Then look for ways to help your furry friend. Increasing physical activity and social contact, as well as learning new tricks, can all boost mental function — as can foods high in antioxidants, such as certain fruits, vegetables or prescription canine diets.

So forget that saying about what you can’t teach old dogs, and get on with some brain boosting.
