Canine behaviour expert Nanci Creedon issued the warning after children in Tipperary and Limerick were injured recently in horrific maulings.
Jack Sage Foran (3) was left with deep cuts to his head after he was “shaken like a teddy bear” after a collie attacked him in Nenagh, Co Tipperary, last weekend.
Abbie Cuddihy (6) suffered serious facial injuries when she was mauled by an American Akita, similar to a husky, on a Limerick housing estate in March.
She needed 17 stitches to a facial wound. Her mother admitted she was shocked by the scale of the injuries she suffered.
Ms Creedon said it has been “a miracle” that Ireland has avoided fatal dog attacks similar to those in the UK and US.
“We are just very, very lucky to have not yet had a fatality. It’s coming, and it’s time we cop on and do what we can to prevent it,” she said.
In the UK and US, the numbers dying or being maimed in such dog attacks has spiralled in recent years. Seventeen people have been mauled to death in the UK since 2005.
