Did you speak to the warden about this, as we are asked to, and then if necessary follow it up with the club?

Yes M.E, I am it total agreement with you, and I think many members will also agree. We use CMC sites a lot because we like the quality of the sites and the excellent booking system, but the only thing that spoils it for us is situations as you have described in your review. To answer your question 'when is the club going to do anything about it' I think the answer is nothing whatso ever. My personal view regarding the guy with the pack of four dogs toileting them in the same place on site every day, is that the club should have a system on their computers and that this action should be reported and he should be warned and entered into the system. Should he get another warning he should then be banned from bringing his dogs on any CMC site. The same should apply to the use of extended leads on site. 

"The same should apply to the use of extended leads on site." 

There is nothing wrong with using an extending lead ,owners need to know when to let the lead out ,and its not when walking round the site 

For clarity the rule says:

Please keep your dog on a lead less than 2m
long at all times when on site other than
when in designated “dog walks”, where leads
may be extended, or “dog areas”, where they
are free to roam. If tethered on your pitch,
please ensure that your dog cannot reach the
road or your neighbours pitch.

And as we all know rulz is rulz. 

If the "problem" as is usually the case ,not reported to the site staff, how can they enter it on a computer if needed?

It is no use any other way of reporting it unless it is the usual anonymous entry/rant which is often found in the site comments book,as on here always after the event

I think the comment from the club sets out the sensible and proper course of action quite clearly but it’s amazing how many people just grumble away to themselves and then rant in a review after the event when it’s far too late for the issues to be dealt with.

If a complaint is made to the warden, what can he/she do about it? If the warden hasn't seen the member allowing the dogs to foul, there is nothing that can be done. If every body complained about the dog fouling on site and expect the wardens to do something about it, the wardens would not have time to carry out their other duties. With regard to the extended leads, the rule is there for obvious reasons but this rule is ignored by most dog walkers on site, even if the warden reminds them about the rule. They can not be on patrol all day, nor should they.

As far as the club is concerned, we all have to accept the behaviour as described in the above review.  

But you wrote this above :

"My personal view regarding the guy with the pack of four dogs toileting them in the same place on site every day, is that the club should have a system on their computers and that this action should be reported and he should be warned"

How do you expect that to be achieved unless the wardens are made aware? 

Also, BS, there is nothing at all to stop you having a polite word with the recalcitrant dog owners in order to help them see the error of their ways. 

You admit the wardens are busy people so why not help them out in the manner of a responsible member?
