Aging doesn’t only occur in humans. Age is something that dogs grasp too. The aging profile of dogs varies from breed to breed and from size to size. Odd breathing, losing appetite, loss of interest are some symptoms of death.  Small dogs are mentioned as senior citizens when they reach 11 years of age.

House soiling, increased barking, and compulsive behavior is the result of getting older. Giant breeds become adults around two years. Glucosamine and chondroitin are required to maintain joint and bone health.
