i agree about dogs running loose getting caught up, but not about dogs in public places being on leads.
i enjoy taking my dogs out to parks/canals/rivers/nature reserves as well as less populated places, the dogs enjoy it even more! they shouldnt have to miss out cos there's a minority out there who cant socialise and control there own dogs.
I no longer take my dogs to public parks because of the number of times out of control dogs cause trouble, my elderly terrier (on lead) near had its guts ripped out by a dog running loose. Did the owner of the large attacking dog give a fuk........
