Gardaí have seized 32 dogs and four horses following a series of planned searches in the Baldoyle area of north Dublin.
The searches were carried out earlier today by uniformed gardaí supported by animal rescue agencies, and were part of an ongoing investigation into illegal puppy farms and related criminal activity.
Among the dogs seized were a number of Chihuahuas, Jack Russells and Pugs.
Gardaí say that six of the Chihuahuas were also pregnant.
All of the animals seized are now in the care of rescue agencies.
Gardaí say the potential value of the dogs recovered is thought to be in excess of €150,000.
They have said there are no planned arrests in this phase of their investigation.
