Seven Pomeranian puppies were seized by gardaí after a car was stopped at a speed checkpoint in Kildare on August 29.
A car was stopped for speeding at the checkpoint on the M7 in Mayfield, Co Kildare, on Saturday, August 29, and it was searched.
The puppies were found in a plastic container in the boot of the car and the driver, an adult male in his late teens, did not have paperwork to account for the dogs and their movements across the border.
None of the puppies was microchipped and were too young to be separated from their mother.
They were then seized by duty officers under the Animal Health and Welfare Act, 2013 and transferred to the care of the Kildare and West Wicklow Society for the Prevention of Cruelty to Animals (KWWSPCA).
"A Fixed Charge Penalty Notice was issued to the driver in relation to the speeding offence," said a garda spokesperson.
"No arrests have been made and a file is being prepared for the Director of Public Prosecutions in relation to the seizure of the dogs.
"Investigations are ongoing," they added.
There has been a huge increase in dog seizures by gardaí in recent months across the country.
In late August, gardaí seized 32 dogs in north Dublin which were valued at more than €120,000.
Gardaí issued advice to pet owners to follow strict guidelines on animal welfare and the security of their pets.
Owners were told to ensure all dogs are microchipped.
The owner's contact details should be logged inside the dog's collar.
