Dogs are susceptible to kidney stones. In fact, our first 2 dogs died of kidney problems. Now we are very careful with salty foods. Although we feed our dogs with cooked food, we are very careful not to put any kind of seasoning. Their food is just boiled meat or boiled fish and sometimes fried food but plain only. And one thing that is good for the kidneys of the dogs is to force them to drink. We use a syringe to force our dogs to drink because it is the habit of dogs not to drink unless they are very thirsty. For a small dog like a pekingese, we make it a point to make them ingest at least 2 glasses of water in a day.
