An unwanted dog with a funny, floppy ear keeps getting overlooked by new owners.
Seven-year-old Zack was rescued after previously not being looked after properly.
But one of the Belgian Shepherd crossbreed’s lug holes bends over.

It is thought to have been caused by an old injury, but it also gives him a unique look.
However, he remains unloved after he can’t attract a new owner despite being in the kennels for four months.
Zack – who weighs a whopping 6st 3lbs (40kg) – was brought in by the RSPCA in March.
He was found the previous October.
The dog is currently at the animal charity’s Great Ayton Animal Centre near Middlesbrough.
An RSPCA spokesperson said: “He came into the charity’s care along with other dogs, after being removed from a home where he was living in poor conditions.
“Zack is seeking a calm, semi-rural home.
“He has a unique look due to a floppy ear, which is thought to be the result of a previous injury.”
Emma Cosby, Behaviour and Welfare Advisor at Great Ayton, said: “Zack loves people and will lean in for a good fuss.
“He is able to settle and relax in the presence of people, but may need time to adjust to being left alone again once he’s in a home.
“He’s an older lad, and after spending time in kennels, he’ll likely want to make the most of human companionship.”
His different-looking ears have left dog lovers amused, as reported on What’s The Jam.
Lisa Jackson said, “Aww, his ears.”
Stephanie Sinclair added: “He is a beautiful dog, loves his ears.”
Ann Dakin said, “What a beautiful boy.
“He deserves a good home.”
