If you are a dog owner, there can be nothing more frustrating than finding your dog has tunnelled under a chain link fence and escaped from the garden. As well as exposing you to liability for having a dog on the loose, your dog may also run into the dog catcher. Reinforce your fence to keep Fido or Fluffy safely inside. Another method is to use chicken wire to stop your dog from digging underneath.

Skill level:

Things you need

  • For each 1.8 to 2.4 m (6 to 8 foot) fence section:
  • 1.8 m (6 foot) sections of rebar
  • 90 cm (3 foot) sections of rebar
  • Hammer
  • 1.2 m (4 foot) roll of chicken wire
  • Wire ties or zip-ties

    Reinforce the fence

  1. 1

    Thread the long rebar along the bottom of a chainlink fence, going through three or four holes, front to back or back to front. This strengthens the bottom of the fence so that the dog can't push it up (they will have to dig a deeper hole to get underneath and will likely give up).

  2. 2

    Space the short rebar evenly apart, threading them vertically through the chainlink. Start threading about 30 cm (1 foot) above the ground.

  3. 3

    Hammer the remaining 60 cm (2 feet) of the rebar into the ground. For example, if you have an 2.4 m (8 foot) fence section, space the rebars at 60 cm (2 feet), 1.2 m (4 feet)and 1.8 m (6 feet). This secures the bottom of the strengthened fence into the ground, frustrating most dogs who attempt to dig under it.

  1. 1

    Roll the chicken wire out along the length of the fence.

  2. 2

    Attach the top 60 cm (2 feet) of the chicken wire to your existing fence with wire ties, laying the other half flat on the ground on the inside of the fence.

  3. 3

    Allow the grass to grow through the bottom of the wire (over time, the wire will become unnoticeable). The dog will not be able to dig through it.

Tips and warnings

  • If you have a gate that swings out as well as in, hammer a 90 cm (3 foot) piece of rebar into the ground like a stake to prevent the gate from swinging out by a dog pushing on it.
