Cows can jump. Just because they are large creatures does not mean that they are earthbound, but that being said, they don't jump often.

In Finland, cow jumping competitions are something of a sport, similar to equestrian show jumping. Cow researchers have commented that as long as the cows land on something soft, it shouldn't be an issue for their body structure, and they're probably enjoying it. Animal cruelty groups raised concerns over the jumping competitions, stating that the jumping was harmful to their udders. However, this concern does not have any scientific evidence to support it, so the sport continues.
