He says the contractor entered his yard

A Texas man has released a disturbing video of a contractor attacking his two dogs with a pipe wrench in the hope that the man is brought to justice.

The horrifying footage was captured on security cameras that Mike Wilcox had installed in the yard of his home in Kingwood, north of Houston.

Taken around 9.45am on March 23, Wilcox said the CenterPoint Energy worker entered his yard unannounced and was approached by his two dogs, Flash and Shutter.

The man can be seen in the video violently swinging a wrench at the the dogs and hitting both of them.

'My wife and kids watched all this from about 5 feet away,' Wilcox wrote on Facebook.

'We filed a complaint with Centerpoint about this and have yet to hear back from them.

'Anyone who has ever met our pets can tell you how they are non aggressive and never bitten anyone! Hoping by post this video we can get them to change their policy on how they handle pets and save the lives of other pets.

'Please share and tag others to make them aware of how Centerpoint will deal with your pets if they come into your yard.'

CenterPoint Energy released a statement about the video, and said that the worker is not a company employee but a contract worker.

Willcox told Click 2 Houston that Flash suffered a concussion, a cut below the eye and a lost tooth.

According to the family, Shutter must undergo surgery for his injuries.

'Honestly, I'm really upset [at] the fact he stepped into our backyard like that and he was swinging to kill my family pets,' Willcox said.

'It just made me wonder how many other times that guy's done that.'
