With the purchase of the old mill in Wehringen, the Müller family laid the historical foundation stone for the Interquell company today. At that time, Nikolaus Müller started operating his flour mill on the Singold.

Edmund Müller produced the first potato flakes. Due to their easy digestibility and good shelf-life, they offered a significant improvement for farmers in pig feeding.

First dog food production started with ‘Müller's dog food’. This consisted of flakes and wet food.

Edmund Müller developed one of the first easily digestible complete food for dogs, consisting of dried meat, maize flakes and vegetables. Müller's dog food brand became Happy Dog.

Happy Dog exported abroad for the first time: to Austria and Denmark.

The first extruder for the production of dog and cat food in croquette form started up and complemented the previous production of food flakes.

Georg Müller (Dipl. oec.) joined the family business in its 7th generation. After the death of the company founder in 1988, he took over the business.

With Happy Dog NaturCroq, Interquell launched the first complete food for dogs in croquette form onto the market.

Happy Dog entered the super premium segment for dog food with Supreme Salmon and Rabbit. The first ‘sensitive’ varieties were Ireland, Toscana and New Zealand.

Interquell developed dry food for cats for the first time: Happy Cat was born.

A new office building, two more extruder lines and a silo tower were built. This created a production capacity of 200 tonnes per day.

Happy Dog Supreme Africa is the first dog food in the world to contain ostrich as a protein source. For every pack sold since then 2% of the purchase price is donated to SOS Children’s Villages in Africa. To date, a total of 1.8 million euros!

Happy Dog became the leading specialist retail brand in Germany in the dry dog food sector.

Goood is Interquell's first premium dog food that is completely climate-neutral - from the field to the bowl.
