Dawlish Loves Dogs has been established in response to a poll to see if dog owners would be interested.
Now, as there were so many people keen to take part, the inaugural event is planned for Sunday September 25.
It will take place at Warren Farm between 11am and 4pm.
A spokesman said: ‘Local dog trainers and experts will be there to talk to and they will be giving talks about what your dog is telling you with their behaviour.’
As well as the dog show, there will be stalls for refreshments and dog-related businesses including trainers, groomers, dog food and accessories.
Parking costs £1 on site although this will be limited so walking is recommended.
All dogs should be kept on short leads.
