You need more than just stalls to make a village fete interesting. A dog show is a good way to get lots of people to come along and show off their pets. You also need displays of various sorts and even a few races for the younger members.
You can have an art exhibition,
dog agility demonstrations,
sack races for the children
or street dancing while the band has a rest.
The dogs and their owners wait to be judged
and later show off their rosettes.
