Most dogs that eat a home-prepared diet don’t drink nearly as much as those that eat bagged foods, because fresh food contains at least 70% moisture. Still, hard-working animals need to be well hydrated to perform well. Dehydration can cause fatigue, poor performance, weakness, muscle cramping, decreased coordination and therefore injury. In addition, dehydration can cause the heart to work harder in an effort to move blood through the bloodstream and risks overheating. So how much is enough and when should you start to worry?
