The RSPCA launched an appeal to find Yogi the German Shepherd a new owner, because visitors kept walking past him and choosing "prettier" animals instead.
Seven-year-old Yogi was born with a wonky jaw and teeth, which make him look a bit strange.

'Unbelievable'
"The response has been unbelievable," said an RSPCA spokesman.
Staff hope to find Yogi a home near Newquay, so they're checking out two offers from dog lovers in Cornwall.
