Pets Are Not Different
Non-organic (and non-wise) approach affects all aspects of our lives. This means that harmful methods of food production influence not only humans, but everything around us including our pets. The present situation with our dogs and other companion animals is pretty similar to the autoimmune issue: there are much more unhealthy pets now than a few decades ago.
This can be explained by the quality of food we feed them: if it is non-organic, an animal would have more chances to lose its strength and finally to catch some disease. It is quite painful to see and take care of a sick pet, but you might easily prevent this by purchasing organics from responsible animal food manufacturer, especially as the number of such producers is increasing every day.
