Signs of Old Age
We've probably all heard that seven years is the age that marks the beginning of the senior years for dogs. In reality dogs are individuals and age at different rates, just like people. Lots of dogs are still going strong and looking young at age seven and beyond, while others do indeed live up to this stereotype. Signs that your dog may be getting old include the following:
Graying of the muzzle and eyebrows
A thinning coat
A drop in energy level
Weight gain or weight loss
More frequent urination
Older dogs also tend to move more slowly because of stiff or painful joints. The lens of the eye becomes hazy, which is a normal part of aging, or is sometimes clouded with cataracts. Teeth become looser and more tartar-encrusted if good dental hygiene isn't practiced. You may notice that your older dog is less able to tolerate extremely hot or cold weather.
