Genesis 7:14

"They had with them every wild animal according to its kind, all livestock according to their kinds, every creature that moves along the ground according to its kind and every bird according to its kind, everything with wings."  Genesis 7:14

As God told them to, Noah and his family had every kind of animal, except of course the sea creatures, in the ark with them.  Even if you say a kind of animal is a general term and referring to a pair of dogs as opposed to a specific breed, that is still a lot of animals.  They certainly had their work cut out for them just caring for the creatures loaded up with them.  At least temporarily, Noah and his family were zookeepers or ranchers.
