Vaccinate your Bernese mountain dog when you first get him and make sure he gets yearly booster vaccinations to maintain immunity to diseases. Also worm your adult dog every three months and consult your veterinarian about flea-control products.
Feed your Bernese mountain dog high-grade dog food. The first ingredient should be meat if you want a quality product. Crude protein should be no less than 30 percent and crude fat no less than 20 percent. Also, the fiber content should be 4 percent or less.
Remember that the Bernese mountain dog needs to spend much of its waking hours with the family and does not do well when left alone in the back yard.
