Older Dogs

The average dog now lives about 13 years, and it is not uncommon to see dogs who are more than 20 years old. The maximum life span of dogs has been estimated to be 27 years. Large dogs have shorter lifespans than smaller dogs. St. Bernards, German Shepherd Dogs, Great Danes, and other giant breeds are considered senior at 6 to 9 years of age and old at 10 to 12. Medium dogs are seniors at 9 to 10 years of age and old at 12 to 14. Toy breeds are consid- ered senior at 9 to 13 years of age and old at 14 to 16 years. Being a purebred or mixed-breed dog does not influence the aging process. A table showing the comparative age of dogs and humans is found in appendix B. However, the numbers are only estimates. Dogs do not all age at the same rate. A dog's biological age depends on his genetic inheritance, nutrition, state of health, and sum of lifetime stresses. Of greatest importance is the care the dog has received throughout his life. Dogs with a poor genetic inheritance may have shorter lives due to medical problems. Well-cared-for pets suffer fewer infirmities as they grow older. When sickness, illness, or injury is neglected, the aging process is accelerated. Adding a puppy to the household can be a rejuvenating experience for an elderly dog. When handled properly, most old dogs delight in the companion- ship. Through renewed interest and added exercise, they seem to recapture their youth. Some older dogs do not enjoy the addition of a puppy. It is best to try things out first by arranging play dates with a friend's puppy or arranging temporary puppy visits, to be sure both dogs are compatible. Prevent jealousy by giving attention to the old dog first. Always affirm the older dog's senior privileges. It is also important to have an area where the older dog can go to be alone when he needs a break from a rowdy puppy. Make sure the elderly dog gets special one-on-one attention every day.
