we have them here,,though i haven't had one in years.think they're about £5 and you need one per dog unless you can get a block(have to claim your a breeder).
the councils do very little about strays but are very quick to let you know when yours hasn't been renewed,well thats how it used to be anyhow.
thats what im saying tho....it just dosent work....nobody would get one and who would police it
and how would you be able to tell wich dog has one and hasnt...unworkble imo
unless thay bring a tax disk in for the dog
