His head hurts every day because of Jin-yeong, a tenant veterinarian who turns the building he bought with all his savings into a wasteland.

Min-sang was bickering with Jin-yeong again one day when he meet an old woman with a quirky personality at the animal hospital, and she was none other than Min-seo, a world-renowned architect.

Delivery driver Jin-woo finds her and saves her, but in the process, Min-seo loses her dog and only family member, "Wanda".

Kim Seon-ho was originally cast in the role played by Lee Hyun-woo, but had to withdraw due to controversy over his private life.

As of March 16, 2024[update], Dog Days has grossed $2.7 million with a running total of 367,182 tickets sold.
