Caring for older dogs comes with challenges, but your bond with your pet means every moment you spend with him matters to you both. That's why you want to give him and yourself as many of those moments as possible. So how can you keep your older dog feeling young? It starts with offering him a high-quality food that is specifically made for his aging healthcare needs, but it's also important to keep him physically and mentally active. If you do those things, you'll go a long way in guaranteeing you and your furry best friend will make the most of his golden years.

When Is a Dog Considered "Elderly?"

It depends on his size and breed. Generally, larger breeds reach mature adulthood and senior status earlier than small breeds. An analysis of 2.5 million dog veterinary records by Banfield Pet Hospital showed mixed-breed dogs weighing ninety pounds or more typically live eight years. That same analysis showed dogs under twenty pounds lived an average of eleven years. PetMD reports that the typical lifespan of large-breed dogs also varies by weight. Bulldogs, mastiffs, and Great Danes have the shortest lifespans (six and seven years) while Cairn terriers, Jack Russell terriers, Shih Tzus and other small breed dogs have the longest expected lifespans (thirteen and fourteen years).

Knowing this will help you understand your dog's changing needs and keep you informed of signs to be on the look out for that he might be slowing down a little and his care needs to change. But it doesn't mean that he can't still be fun and lively. Read on to learn about the signs of aging, and what you can do to keep him as full and vibrant as he was in his young adult days.

What Are Signs of Aging to Watch For?

Older dogs exhibit many of the same signs of aging as humans. Watch for:

• Vision loss. Cataracts, glaucoma, progressive retinal atrophy and sudden acquired retinal degeneration are the most common causes for vision problems in aging dogs. Caring for dogs with vision problems can offer a special set of challenges for the rest of the family, but certainly doesn't mean a poor quality of life.
• Oral problems. Tartar, gingivitis, and tooth and gum disease are all serious health issues for dogs. Banfield's study reported small breed dogs (including dachshunds, Yorkshire terriers, Shih Tzus, and Maltese) have the highest prevalence of dental disease. Left untreated, these issues can lead to infection, tooth loss, bone damage and oral pain. Talk to your veterinarian if your dog exhibits symptoms, such as bleeding gums or bad breath.
• Weight gain (or loss). Older dogs who are in pain tend to get less exercise, which can result in weight gain. Conversely, if you have a dog that is inexplicably losing weight, it could be the result of dental, stomach or other health issues.
• Joint pain. Arthritis in older dogs is one of the most common health problems seen by vets. It can be difficult to diagnose because dogs often show only subtle signs of the pain they are experiencing. As a pet parent, you can look for signs of arthritic pain, such as less interest in playing, caution in climbing stairs or jumping on furniture and weight gain.
• Senility. PetMD reports clinical signs of cognitive dysfunction are found in 50 percent of dogs over the age of 11. Some common signs include disorientation, anxiety, inability to follow familiar routines, lack of self-grooming and house soiling.
