Many of the dogs were Chihuahuas or Chihuahua crosses.
Nearly 40 dogs were rescued from a flat in Surrey where they were living in cramped conditions.
The RSPCA rescued the 39 dogs, many of whom were Chihuahuas or Chihuahua crosses, from the Surrey property last month.
RSPCA Millbrook in Chobham has been caring for 27 of the dogs and the others are being cared for by other RSPCA centres and branches. With some TLC, many of them have now been rehomed but Bobby, Ziggy and Boo are still patiently waiting.
