When the dogs take over the pool, that marks the end of the swimming season.

The annual Doggy Dip will be held at the Platteville Family Aquatic Center Sunday, with small dogs swimming at 6:30 p.m. and large dogs at 7 p.m.

The cost is $7 per dog, with all proceeds going to maintenance and improvements in the Platteville Dog Park. All dogs must be accompanied by a human adult.
