The "Scoop that Poop" campaign began last week and was being stepped up this week, council acting chief executive Louise van der Voort said.
She said the council had noticed a "growing concern" about the problem of dog droppings in public places.
"Some residents are totally fed up, which resulted in one customer gifting us a parcel of poop at the front reception in Alexandra last week.
"In response council had "increased its promotional efforts" with its latest "anti-fouling campaign", she said.
This week, a text was sent to nearly 2000 dog owners saying: "Central Otago dog owners. Residents are grumpy about dog poo littering our towns. Not your dog? OK, but please ALWAYS pick up after your dog. Failure to do so = $300 fine. We love dogs, we hate seeing dog poo. From the CODC team."
Ms van der Voort said "the majority of dog owners get it but, as is often the case, a few are spoiling it for many".
"We are reminding people that if they can’t clean up their act (and their dog’s business) then they leave council no option but to issue fines. If your dog is witnessed pooping and you don’t pick it up, expect an infringement fine through the post."
