To give a senior dog its best life, keep them at a healthy weight, as obesity is the scourge of not only the American population but our pets as well, with more than 50% of dogs being overweight in the U.S. According to a Purina Lifespan Study, you can pretty much plan on an overweight pet living 2 years less than they would otherwise. Taking your pup to the vet for regular check-ups, especially as they age and become more prone to certain diseases, can help identify health problems before they become serious. Maintaining joint health is also crucial, as dogs' joints tend to get stiffer and more painful as they age, and keeping your dog at a healthy weight will help, as added weight only adds more strain to already sore joints. A good theory to keep in mind when approaching exercise for your elderly dog’s body and mind is: “If they don’t use it, they lose it.” Staying physically active is crucial for older pups to maintain muscle mass and keep their hearts pumping well. Providing mental stimulation is equally as important, and activities that challenge your older dog’s mind will help them stay sharp. Nutrition is especially important for older dogs to help them fight disease and increase their lifespan, and feeding a high-quality diet can make a big difference.
