A desperate dog owner is offering a £2,000 reward as the search for his beloved pet enters its second week.

Jim Effeny believes 18-month-old English bull terrier Bow could be in Gravesend or Dartford after running off during a walk.

The 39-year-old, from Thurrock, last saw her in Belhus Country Park, Essex, at 11am on Saturday, December 30.

Since then he has been camping out in the park in the hope that Bow, who he got as a birthday present when she was a puppy, will come back to the spot.

He said: "I will often walk her off the lead but make sure she's put back on if we come across anyone.

"Bow was seen around 6pm about a mile away by Dennises Lane underneath the M25.

"She's vanished and I've had 100s of people out looking for her and there have been no reports of dogs killed on the roads which makes me think she's been stolen.

"If she was taken by where she was last seen there's a good chance she will be in Kent as she'd have been driven over the Dartford Crossing."

Bow is a familiar face to many dog lovers in the county, as she often leads walks for the Kent branch of Absolute Bull Terriers.
