"If it was a child they wouldn't have had a show. It was just that I had the chain so I could work my way up and grab the collar before jumping the fence."
The dog was roaming across from a school, which concerned Mr Hopkins.
"Something has to be done as everyone walks around these areas.
"It is a growing problem which was proven yesterday when I saw two cats dead in the park. One on the south side and the other on the north side."
Mother and son Maureen and Doug Goodall were the owners of one of the cats found dead.
Both were saddened by the experience.
"By the amount of footprints around our cat it looked like there was more than one dog," Mr Goodall said.
It was a risk to go out on the street after 8pm with the number of dangerous dogs roaming now out of hand, he said.
"I can't even take my dog for a walk any more."
Mr Goodall has since been in contact with the Hastings District Council because he wanted some sort of patrol in the area, especially at dusk.
"By the time animal control do arrive the damage has already been done anyway."
A council spokeswoman said the team worked 24/7 and just on Sunday night received a call at 10.35pm from a man in Flaxmere.
"We do encourage people to call us with reports of dogs wandering at the time they see them, providing us with as much detail as possible such as description and where they were last seen heading."
Mr Goodall hoped something more would be done soon so a child would not be hurt.
"I think people would then sing a different story, something has to happen to stop this."
