The Coast Guard, which is a voluntary service, were then called to rescue the dogs from danger.
The team managed to rescue the dogs in a daring manoeuvre, which involved setting up a cliff-top anchor and sending a climber to the edge.
The dogs were then put in a large canvas bag and secured to the climber, then set on to the beach 50m below -- where their relieved owner Caroline was on hand to welcome them back to safety.
The entire incident required eight coast guard officials at the scene to decipher a rescue plan. As the service is a voluntary one, there were no costs involved.
There was no obvious route for the dogs to have made their way down the 30m distance to the ledge of the cliff, which made their rescue even more of an ordeal.
"The dogs are very highly strung and they seem to have a fascination with birds and rocks. They are very adventurous and I think they wanted to follow the seagulls but got caught on their travels," Caroline said.
She has often found the fun-loving pair wandering the area in pursuit of adventure.
"They love walks and take any excuse to run off on their own. I have often found them in the nearby golf course and reservoir just running around."
Caroline expressed her concern of the recent dognappings plaguing the capital and is thrilled that her dogs were returned home to safety.
"With all the dognappings, I was slightly worried. Somebody could have easily taken them and put them into the back of their car.
"But we are absolutely delighted to have them home now, safe and well," she said.
Both dogs are in perfect health, in spite of being a little tired and stiff from the ordeal.
"I would like to say a big thank you to the Coast Guard, who were such a help."
Howth Coast Guard would like to remind members of the public if they see anyone who they think may be in trouble on the cliffs, beaches or at sea to please dial 999/112 and ask for the Coast Guard.
