It's no secret that the pet industry has grown tremendously over the last 10 years.

Pet owners are spending more money than ever on their canine companions.

Not only are we spending more money, but we're also pushing for companies to create unique products to meet every dog-related need.

The biggest dog companies in the world are meeting those needs and then some.

According to the American Pet Products Association, $95.7 billion was spent on pets in the United States in 2019, and $99 billion is estimated for 2020.

The specific breakdown of this spending looks like this:

  • Food – $36.9 billion
  • Supplies and over-the-counter Medicine – $19.2 billion
  • Vet Care – $29.3 billion
  • Live animal purchases – $2.1 billion
  • Pet Services (grooming, boarding, etc.) – $5.76 billion

Here's how rapidly this industry has been growing: In 2006, Americans spent just $38.5 billion on their pets, and in 1996 that number was only $21 billion.

We spent more on just the top dog foods alone in 2016 than we spent on all pet products a mere 20 years ago.

But who's profiting the most in the pet industry? Let's take a look at some of the biggest dog companies in the world and the products that they manufacture.

 Biggest Dog Companies

Top Dog Food Companies

Unless you've been living and shopping in a cave, you will certainly have heard of each of pet food's big four corporations. Between these big four, they own almost all of the best-known dog food brands.

1. Mars Pet, Inc.

The largest of the big pet food corporations is Mars Pet, Inc. 

Mars owns household dog food names, most of which are very familiar to pet owners in the U.S. and are some of the most commonly purchased and recommended, such as these popular dog food brands below:

  • Pedigree
  • Cesar
  • Chappi
  • Frolic
  • Pal
  • Nutro
  • Greenies
  • James Wellbeloved
  • Royal Canin
  • Royal Canin Veterinary Diets

2. Nestlé Purina PetCare

The second-largest pet food manufacturer is Nestlé Purina.

The name probably rings a bell more for its brand of chocolate.

However, Nestle owns and manufactures large dog food brands like Bakers, Bonio, Winalot, Beta, ProPlan, Beneful, Purina One, and Purina Veterinary Diets.

3. Hill's Pet Nutrition

The third-largest dog food company is the famous Hill's Pet Nutrition.

Hill's Pet Nutrition is also home to two of the largest vet-recommended and vet-supplied dog food products worldwide.

These are Hills Science Plan and Hills Prescription Diets, both of which are often recommended by veterinarians.

4. Spectrum Brands/United Pet Group

Finally, the fourth largest pet food company in the world is the lesser-known Spectrum.

Spectrum is home to two huge dog food brands that are very well-known and respected in the US – Eukanuba and Iams.

How They Became World Leaders in Pet Food

Why are they the world leaders in pet food?Without digging too much into the business terminology, analysis, and history, the answer is quite simple – they got there first, or other huge conglomerates purchased them with large net worth.

Today, these world-leading largest dog food manufacturers can afford expensive TV advertising, unlike many smaller and newer pet food brands.

They can also afford the terms imposed by supermarkets. Thus, they receive the most exposure. They also spend millions on inventing new dog food formulas.

This is probably why, even if you’ve never owned a dog, you can still recognize some of the names in the above lists.

On their journey to becoming one of the big four dog food manufacturers, these pet food companies have managed to buy out the most successful independent brands to expand their product range.

Adding To The Brand

They continue to buy new pet food brands almost monthly.

Together, pet food companies have also effectively invented veterinary diets and now controversial prescription dog food brands.

By creating dog food directly for vets, 9 out of 10 vets now recommend foods from one of these top four companies.

That is not to say that every brand of vet-recommended dog food must always be bad since companies spend insane amounts of money on testing what works best for a dog's health.

However, except for a few well-respected dog food brands, a lot of them are low quality.

With a large expenditure on advertising, supermarket special offers, and retailer incentives, you might be right in thinking that less money is spent on ingredients in their dog foods.

Depending on which type of dog food you're currently thinking one, one look through the ingredient lists of two of the biggest dog food brands, Pedigree, and Bakers.

Clearly shows that effort is pumped more into the marketing of these dog foods and is a major credit to the brand's success over the quality of the products.

Top Dog Toy Companies

Top Dog Toy Companies

Dog toys have changed over the last few years. There are thousands of great toys for dogs to choose from, and most pet owners prefer to buy their dogs various things to play with.

Whether your dog likes rope toys, stuffed toys, or treat-dispensing toys, you've surely heard of these large companies that made huge leaps in this industry area.

Unlike dog food companies, manufacturers of dog toys usually have a much better reputation among dog owners.

Mostly it's because their products aren't consumable, and the quality of the dog toy is directly related to how popular the brand is.

Biggest Dog CompaniesKONG is one of the fastest-growing dog toy companies today, manufacturing some of the best high-quality KONG pet toys and gaining solid respect from dog owners worldwide.

KONG’s founder, Joe Markham, loved his retired police dog, Fritz, but did not love his destructive chewing habits.

Fritz loved to crunch on rocks, sticks, and other harmful items, causing his teeth to wear down.

His need for stimulation and play was not being met.

One day, while working on a VW Bus, Joe began throwing out car parts to Fritz to lure him away from the rocks.

Fritz was immediately taken with a rubber suspension part and dropped it in Joe’s lap to play.

The erratic bounce and toughness of the rubber inspired Joe.

Now, KONG Company creates its own proprietary, pet-safe, built-to-chew rubber dog toys. Durable, fun, and safe to chew, dogs and owners love KONG.
