Four dogs are still waiting for homes after being with Auckland's SPCA for more than six months - equating to a seven-year sentence for humans.
SPCA chief Andrea Midgen said it was rare to have so many dogs in care for so long.
"Generally they would be here for two or three months.
"Every now and again we get one, maybe, that is a bit of a long-termer, so to have four is a bit unusual."
