I fully agree with TV One's news item on gassing of surplus impounded dogs. There are far too many cats and dogs in NZ.

Some have caused horrendous injuries and deaths to children and adults, plus many have bitten their owners. Every dog on our planet has wolf genes passed down over eons, hence their aggressiveness at times, the wild instinct.

Don't forget the large amount of faeces and urine, creating problems everywhere they roam.

I strongly object to dogs licking people's faces. It's is amazing there's not more diseases from the objectionable act, as dogs are seen licking their privates, cats also. Dog's noses and tongues have thousands of germs and bacteria. Police, guide and custom's dogs are essential, also farmer's dogs.
