Old Age and Senility in Dogs

It was more than 17 years ago that we first learned about the fine work of S.J. (Jim) Harless, DVM, in the field of geriatric canine and feline senility. The doctor's
inspiration came from clinical studies of senility in humans and very positive results from a dietary treatment called "choline loading." Human and canine serum
and, hence, livers and brains can suffer from reduced levels of the neurotransmitter acetylcholine, which is a metabolic product of dietary choline. One of the richest
sources of choline is soy lecithin and is a constituent of most choline supplements on the market today. Dr. Harless helped create a very special dietary supplement.

First, let's define what is meant by "senility" as it appears in a respected medical dictionary: Taber's Cyclopedic Medical Dictionary, Edition 19.

"Mental or physical weakness that may be associated with old age."

Senility in dogs can usually occurs as the pet approaches the final third of its expected longevity. Length of life depends on family genetic factors as well as the
physical state of the animal, i.e., its health. The following case is from the author's own experience with an incredible Norwegian Elkhound, "Randy."

A 14 year old Norwegian Elkhound was becoming lethargic seemed depressed; i.e., didn't respond happily to mealtimes, a walk in the woods, his owners' homecomings, playing fetch with a ball or toy, etc. His diet was very low in carbohydrate; less than 10%, high in protein; 65% and fat; 14%. "Randy" had thrived on such a diet since about 4 months of age. His physical health was excellent, except his muscle mass was slowly depleting due to lack of exercise. He had been neutered at 4 years.

Within 6 weeks of supplementing his diet with the product named Cholodin(tm) Randy started a comeback that amazed us. He started initiating play by getting a toy and bringing it  to pester for playtimes, his appetite soared, his activity level was nearly puppyish. He remained both healthy and active until a sebaceous cyst created
discomfort at age 17 yrs 3 mos. At that time his activity level began slowing and his veterinarian predicted he was fading fast from his normal aging process. When Randy was almost 18 he could no longer function normally; i.e., squat to defecate without toppling over. He acted as if he felt miserable. He was humanely put down. Curiously, at the moment of death Randy's tail was wagging vigorously!

Dietary choline loading is used for various problems in dogs and cats, including improving liver function, epilepsy,  behavior problems, as well as senility. Here is
an excellent source of further information on the internet:
