I indeed agree that dog owners in the area need somewhere "safe" to exercise their dogs.
London as a whole is limited to where you can do this, however such facilities are usually abused by dog owners too.

Dulwich park for example, where people feel there is not need to clean up after their dogs in the designated "dog exercise area" As a result of which... IT STINKS!!

As a dog owner I would like to see safer places I can exercise my dog without the risk of parents allowing uncontrolled toddlers to run over and shove their hands in his mouth, while mum or dad sends a text......
