Now today we’re talking about seven of the worst kibbles you could possibly feed your American Pitbull Terrier Puppy.

How Kibble Is Made

Kibble is made using a number of ingredients that have undergone various processes.

The primary ingredient used in kibble is rendered meat byproducts. This can be from livestock horses and euthanized pets.

Rendering is a process that uses heat to separate the water and fat from the meat solids. The solids are ground cooked and ground again. So it becomes a meat meal.

The meat meal is then mixed with cereals and grains corn, gluten feed, and sometimes ground fruit and vegetables.

Then preservatives, stabilizers, and gelling agents are added plus synthetic vitamins and minerals to replace those lost in processing.

Palatability can be enhanced with yeast, fat, sweetness or concentrated flavors liquid is added to the dry mix to form a dough.

This is then cooked under intense heat. And then pushed through an extruder where it is then sprayed with a coating for color and flavor.

This is how kibble is made regardless of the manufacturer and regardless of the ingredients used.

What’s the Problem With Kibble

Kibble is processed multiple times at extremely high temperatures effectively, killing valuable vitamins and enzymes which then have to be replaced.

Stabilizers, preservatives, and gelling agents are needed to keep the product shelf-stable and to avoid mold and deterioration.

It’s unlikely that the manufacturer would know where the meat product came from originally or what indeed the meat produce was in its original state.

Kibble is gray so it needs to be colored to make it more acceptable for pet owners to buy and to feed.

Kibble does not store well. As soon as the bag is opened fat’s in the food start to go rancid. And this can obviously have a very negative effect on your pet’s health.

Kibble that contains grain may also include mites that live in the grain. Resulting in itchy skin hair loss and ear infections.

11 Bad Ingredients in Dog Food to Avoid

Gluten (Wheat, Corn)

  • Gluten is found in different types of cereals such as wheat, corn, etc.
  • It’s used as binders to form the kibble.
  • It is highly allergic and can cause gastrointestinal problems and obesity in dogs.

Corn Syrup

  • Excessive consumption of this can lead to weight gain, obesity, and diabetes.


  • This cheap ingredient is used as a replacement for animal protein but has poor quality.
  • The problem with soy is that it is not a healthy food even for people.
  • 90% of soy has been genetically modified and high levels of pesticides have been found in this.

Meat Meal

  • “Is the rendered product from mammal tissues, exclusive of any added blood, hair, hoof, horn, hide trimmings, manure, stomach, and rumen.” AAFCO Association of American feed control officials.
  • Of course, all this disgusting mixture results in a poor quality of protein and low nutritional value for your dog.

Meat By-products

  • “It is the non rendered, clean parts, other than meat, derived from slaughtered mammals. It includes, but is not limited to, lungs, spleen, kidneys, brains, livers, blood, bone, partially de-fatted low-temperature fatty tissue, and stomachs and intestines freed of their contents”. AAFCO

  • It’s a pet food preservative
  • Although the FDA has not determined that it is dangerous dog owners report effects such as allergic reactions, skin problems, organ failure, behavior problems, and cancer.

  • Cellulose obtained as a pulp from fibrous plant materials.
  • Used as a cheap binder, stabilizer, emulsifier, and anti-caking

Seven Worst Dog Foods for American Pitbull Terrier Puppy

Let’s get right into the list of kibbles that are bad for your dogs


Beneful by Purina

  • Too many fillers used.
  • Corn listed as the first ingredient.
  • Use of potentially dangerous ingredients.
  • Too many negative customer reviews.

beneful by purina

Now the first kibble on my list is Beneful by Purina.

It does contain chicken as a protein source. But it’s also full of soy and wheat. And these ingredients could develop serious digestive and health issues over time.

They do have some questionable by-products such as chicken. So that’s why I put this as number one on the list.

Kibbles n Bits

  • Use of filler ingredients like corn
  • Contains little nutritional value
  • Indeterminate meat content
  •  Low-quality ingredient
  • Contain numerous synthetic dyes

Number two on the list is Kibbles n Bits.

Now the number one ingredient on this is corn. That’s one thing that pops out to me there’s also beef and bone meal, soybean meal, wheat, and flour.

But I did notice that this kibble and bits are missing natural meats inside of their ingredients.

So that’s the reason why I say stay away from this brand. And their ingredients also have numerous synthetic dyes. That’s another reason why I say stay away from this.

Iams Dog Food

  • Made with meat byproducts and fillers
  • Some processed, unnatural ingredients
  • No gluten-free option
  • May cause stomach upset or bloat

While chicken is the main source of protein for Iams, it also contains chicken by-products.

It also includes cornmeal and whole grain sorghum. Another ingredient that I saw on this is they use dried beet pulp. This ingredient is used as a sugar filler. And it can also make your dog gain some weight.

Purina Dog Chow

  • The main ingredient is grain corn
  • Contain artificial coloring agents
  • Contain unidentified meat
  • No probiotics
  • Near-average protein
  • Below-average fat
  • Above-average carbs

The main ingredient in the Purina Dog Chow is grain corn. There’s also some poultry by-product meal that we do not want in there. Also contain meat (from unknown origin) and bone meal, whole-grain meal, and soybean meal.

And I did notice this kibble does use four different dyes to maintain the color for their kibble. They use a lot of corn and a lot of greens with a lot of dyes. Overall this is not good for puppies or adult dogs


  • Use Chicken by product
  • Contains sugary beet pulp
  • Also has citric acid
  • Ingredients can cause digestive problems

Now the dog food formula is natural but that doesn’t mean it’s necessarily good.

They use their protein as a chicken by-product meal instead of a wholesome chicken.

It also contains sugary beet pulp and citric acid. Overall this is not good. This could cause digestive problems and a lot more health issues down the road.

Ol’ Roy Dog Food

  • Does not contain any protein sources
  • Uses Ground yellow corn, meat and bone meal, soybean meal
  • High concentration of meal corn
  • Use preservative such as citric acid

Now, this doesn’t have any kind of protein sources. Instead, they use ground corn, soybean meal, ground wheat, and meat.

Meal corn is also listed as the first ingredient. So it has the highest concentration inside of this kibble.

Citric acid is also used as a preservative. So this could cause some dental issues with your dog some digestive issues and overall health problems

Pedigree Adult Complete Nutrition Dried Dog Food

  • Low nutritional value
  • Main ingredient is corn
  • unnamed meat by-product meal
  • Near-average protein.
  • Below-average fat.
  • And above-average carbs

Now the closest thing they have to protein is a chicken by-product. The byproduct isn’t great it could come from unwanted leftovers from a variety of sources.

Ground whole grain corn and corn gluten meal are also used in this kibble.

And there’s also a variety of synthetic colors utilized in this kibble which overall makes it unhealthy for your dog.
