The puppies are 8 weeks old
Six puppies have been discovered in the boot of a car at Dublin Port during routine checks.
The DSPCA says they were destined for the UK and would have remained in the sealed boot for the entire journey on the ferry with no access to water.
The DSPCA says this is not an acceptable method of transport for any animal.
The puppies are terrier crosses and are about 8 weeks old.
They're not microchipped and don't have vaccination certs.
They're now in the care of the DSPCA and will be placed on foster care until they are ready to be rehomed.
The DSPCA says it would like to thank Revenue officers at Dublin Port for their vigilance and their continued efforts to end this cruel trade.
