One of the most common questions veterinarians hear is whether or not a dog's symptoms or behavior are due to old age. Owners attribute a wide range of symptoms to old age. Whether it be sleeping all the time or drinking more water, many owners overlook the possibility of other causes. Even weight gain and weight loss are excused away as caused by the aging process. It's true that changes do happen as dogs age; sight and hearing may be diminished, and dogs may sleep more. These are expected changes. But other changes ought not to be discounted.
Owners often miss potentially serious signs of illness in their dogs, when in fact a veterinary exam is in order for your dog. Even though changes are inevitable, there are many signs that are never considered normal at any age. Have them checked out by your veterinarian to rule out underlying disease, injury, or illness. Even as your pet enters the senior years, assume that most conditions that arise are indeed treatable.
What Age Is Considered Old?
A dog is considered to be a senior after age 7. (This varies by breed, and giant breeds are considered senior at 5 or 6) An annual veterinary examination is essential for keeping your dog in optimal health and staying on top of all age-related changes. But as with people, dog health is less about age and more about a body's particular array of challenges.
People may argue that, in the case of advanced age, an extended treatment regime would not add any more quality to the dog's life. This may be true, and it's something to discuss with your veterinarian. It is important to note, however, that a pet may simply seem older due to an illness. Once a dog is restored to health, it may indeed act like a puppy or kitten again.
Normal Age-Related Changes
The same normal progressions occur in our dogs that occur in humans. Here we focus on only age-related changes, yet this is not a comprehensive health checklist. Any time that you notice a change in your dog (at ANY age) that you are unsure of, please call your veterinarian to discuss.
- Graying of the fur on the muzzle, increasing slowly with age
- Less active overall
- Sleeping more
- Reduced sense of hearing
- Reduced sense of sight
- Less able to handle temperature extremes
- Reduced muscle mass
- Increased discharge from ears
- Dark-colored matter in ears
Disease Symptoms Commonly Mistaken for Old Age
Some changes may be symptoms of a disease process or an injury and not just old age. If you notice any of these symptoms, a call to your or veterinarian is warranted:
- Loss of appetite
- Foul breath/dental disease
- Vomiting, diarrhea, constipation at any time
- Drinking and/or urinating more than usual
- New behavior such as growling, biting, or scratching people or animal friends as if they are not recognized or unwelcome
- Walking or moving in a jerky manner, losing balance or falling down
- Legs sliding out from under when on carpet or on non-slip floors, or favoring a leg after slipping on a slippery floor
- Favoring a paw, or more than one, chewing on it, or licking it when no cut or injury is visible
Skeletal Body Changes
- Weight loss or gain
- Laying with odd body positions as in hind legs splaying out when that has not been a position before
- Stomach or chest looking unusually bloated or having lumps or strange concavities not noted before
External Body Changes
- Increased discharge from eyes and or pink color in whites of eyes
- Swelling of mammary glands or nipples in male or female dogs
- A patch of skin or fur that is discolored, especially if it has come about quickly
- Swelling that is dry or swelling that has a discharge
- Deliberate scratching of an area, continuing for more than a few hours
