Beware of tricks from pet food manufacturers
Pet food companies are in the business of selling foods and there are tricks of the trade to sell more. Often, volumes to be fed on these bags are too large. This means you buy food more often than needed and your pet may become overweight.
Sometimes foods have more fat and salt in them than needed to enhance flavor. The more willing your pet is to eat a particular diet, the more likely you are to continue to purchase that brand.
The ingredients list on the package does not have to change every time the ingredients inside the bag change. Most foods will also list a minimum fat content. The label may say a minimum of 7% fat, but no maximum is listed. There could be 30% or more fat! Only the manufacturer knows for sure.
Many of the common phrases seen on packaging such as “Low Fat”, “Low Calorie”, Natural”, or Grain Free” have no legal implications. In other words, what is on the package, may not mean anything worthwhile.
