Dogs in Germany will not be able to be left home alone all day, and someone will be required to look after the pet "several times a day".
"Dogs are not cuddly toys. They also have their own needs, which need to be taken into account," Klöckner said.
The new law has caused controversy in Germany this week. Many wonder if it would be possible for the government to check on the 9.4 million dogs in the 19 per cent of German households with dogs as pets.
A spokesperson for the ministry of agriculture clarified it would be up to the local state authorities to enforce the law.
However, even people within Klöckner's own party, the Christian Democratic Union, have openly criticised the law.
Saskia Ludwig, a CDU MP, pointed out some dogs cannot cope with being out in the current heatwave the country is under.
"VOLUNTARY DISCLOSURE: I will not be taking my Rhodesian Ridgeback for two rounds of walks in 32 degrees heat, rather we will jump in the river for a refreshing cool down instead," the MP tweeted.
