Because of the design of the dog food product, by type of  raw material, raw material costs, market factors and other factors, sometimes some high fiber, minerals, crude ash may be used, which affects  palatability. Sohow to meet both of the dog's physical needs and maintaining  the taste of dog food? After trial we draw the following conclusions:

1. Many dog food manufacturers mistake that dogs prefer salty to sweet, which is a common phenomenon . In fact, in the choice of savory at the same time dog prefer a touch of sweet child, so in the production of dog  food, it is perfectly appropriate to select some of the sweetness;

Many dog food managers often ask why they add so many attractant, but effect is not obvious? I want to  emphasize here: palatability of damage must be completely repaired.

3, To improve palatability attractant choice. Professional expertise on the market for dogs, dog food attractant, attractant liquid part, the quality is different. We focus on several types of products. Raw material  composition, the carrier source, adding the proportion of high-temperature type and other factors. A good dog food attractant lies in its color, its taste. To test how good in general attractant will be adding some type of  raw materials such as animal liver, so it is important to sources of these raw materials, whether fresh, whether pure.

4, The first aspect that impact dog feeding is taste, but more important is the dominant
