Dr Katrina Warren is sick and tired of dog owners not knowing the correct etiquette when it comes to their pets.
In an Instagram post in October, the TV vet - best known for co-hosting Harry's Practice - explained how she's baffled by the number of owners not putting their dog on a lead.
"Why has this become so difficult? Do people now buy a dog and forget to buy a lead?" she wrote.
"Your dog should be on a lead at cafes, walking on the footpath and at parks that are NOT designated off-leash. It’s for your dog's safety, as well as the safety of other dogs and people.
"I've witnessed some dangerous things with fights, knocked-down tables, terrified kids and boiling coffee going all directions, as well as timid dogs and puppies being terrified."
