Just because these dogs were not on a lead doesn't mean they were out of sight of the owner nor out of control. For certain breeeds of dogs lead exercise is not enough. It takes literally seconds for an animal to eat something and one would not expect a large amount of pizza dough to be dumped on public ground. For those of you who cannot sympathise with the dog owner, then what about other wildlife that will probably have been killed by this TOXIC waste. At the end of the day this person is nothing but lazy lowlife who needs to be brought to task so once again if anyone out there knows who it is then the sooner he is caught the better !
