Beagles bred for laboratory testing are cooped up at a UK puppy mill in small cages covered with excrement, footage appears to show.
They pace up and down, showing what campaigners allege is the kind of “repetitive stereotyped” behaviour of animals enclosed in too small a space.
As many as six dogs can be seen in some cages, with little bedding and just a few toys attached to the side of the enclosure. It was not clear if other cages out of view had fewer animals in them.
