is there different in various pet food?

The different foods are not created equally. The cheaper foods contain a lot of fillers like corn and wheat, really not the best they also contain less quality proteins and instead tend to use a lot of animal by-products. I don't think there is much if any value to the foods containing vegetables as dogs by nature are carnivores and not omnivores. Recommend you look around and read the ingredients. If you read the ingredients list the ingredients are listed in order of the biggest to smallest concentrations. Technically the closer the food is to the pets natural diet the healthier it is for them. Dogs of course need as much quality animal protein as possible, the corn fillers only add to obesity and cut down the protein they are getting so yes theoretically those cheap full of filler foods can potentially cut the life span of your pet. The big vs small dog foods difference would be the size of the kibble. The cost of many of the pet foods out there is in part at least related to marketing so I don't think the most expensive is always the best choice. Read the ingredients because many times the middle cost foods can be every bit as good as the most expensive.

The wheat gluten is not the crisis. They are involved that the specific wheat gluten they (Menu Foods) purchased from a brand new provider was once infected, with what, they have not discovered. Supposedly, it was once no longer used within the different forms of dog food. And intriguing be aware, in a quarterly style scan Menu Foods did on there product, nine cats died. This scan was once no longer performed in view that of buyer proceedings because the corporation had beforehand recounted. Nor do they state precisely while the movements style scan was once performed. I surprise how lengthy they knew it was once killing pets earlier than they recalled their product.

Yes, there are different types of dogs foods and not all are good hence always be careful of what you feed your dog.

Stay away from any dog food containing corn.

Because of the manner in which ALL corn is stored, there is no corn that is not contaminated with mold (even if you can not see it). The mold produces toxins. The mold toxins cause cancer. Therefore, no animal (and no human, either) should ever consume corn.

Taste of The Wild and Blue Buffalo are good brands.
