Larger breeds hit the senior years a lot faster than little dogs, so find out when your dog is official a senior so that you can start a senior citizen protocol with your vet.
The proper food and medical tests will keep your senior healthy and happy in their golden years.
Once your dog is a senior, you should have your vet perform an abdominal X-ray at least once a year to watch out for tumors, a complete blood work up to watch out for organs that might be getting cranky and not functioning properly, and a prostate exam on male dogs (especially uncastrated male dogs) to make sure the prostate is not enlarged, and to rule out adenomas.
Spaying and neutering are VITAL for a senior pet's health. If performed while young, the risks of cancers and health problems decrease.
