Walking on the beach in Florida with my Lhasa Apso adult dog Angelia: She was an ideal pet, and lived almost 16 years. She passed away just from old age. My theory is she lived full life without ever getting sick because I brushed her teeth daily with a soft brush and no toothpaste. The mouth germs can reach kidneys and heart and cause premature death. Cleaning every 6 months at vet's office is never enough. If we humans did not clean our teeth daily, we can also have problems with heart valves and kidney function.
