This lovable giant is in kennels but hoping to find a new home soon.
Zack is a four-year-old German shepherd/rottweiler cross.
A spokesman for Wellidogs, which is caring for Zack, said: “He can be stubborn and quite nervous but is starting to come out of his shell and loves to play with a ball and have lots of cuddles.
“As he can be quite stubborn and strong we would recommend that anyone interested in him has had some experence with big dogs.”
