Please tell me to calm down!

Just put a note on it, maybe they don't know that it bothers you.

At least it was put in, I assume, the General waste bin.

My neighbour had a bag of dog poo put in their recycling bin, and it was checked and not emptied.

She was livid, put a strongly worded note on top of said bin for any dog walkers.

We have the same problem and ha ve now wired the bin lid down which is a bit awkward for me to undo, but it works.
Yes it is annoying.

If you had CCTV on your premises, could it potentially monitor the bin.

I am not talking about actually getting CCTV, but if you could put a note on the bin telling them not to chuck dog shit in , followed by a statement saying CCTV is being installed. That might work.

I'd be cross too. I would probably do as Kadinsky says and get up to see who thought this was ok. I would ask them in person to stop.
I hate dog poo bags festooning trees etc and would be seriously annoyed by someone doing this.
Sorry, not the calming you wanted from me - write a note at least!

Is there any way you could attach a lock to the bin? I think this is really unacceptable behaviour .. at the very least tape a large notice to the lid of the bin..

I'd feel the same I wouldn't want dogs poop in my bin even it it was bagged.

I’d feel exactly the same!

In fact, I’d get up early to see who’s doing it and go out & tell them to remove it!

Bloomin’ cheek.

The same happens to me my bin is used for blooming dog walkers to stick their smelly dog poo bags in if I don’t rush out to get it in

I’d be furious too Romola.
The wording I’d use on the bin would be
‘This is not a public waste bin. Please take your dog’s waste home with you.’
I’d be tempted too, to use a less euphemistic term than ‘dog waste’.

Yes, I agree - leave a notice.

Apart from the suggestion of putting a note on your bin or getting it in as soon as it has been emptied not a lot you can do so perhaps time to stop getting furious about it. Is it really worth it it's a bin?
Can't say I pay much attention to mine once they have been emptied life's too short.

Calm down! Though you have every right to be annoyed. You could try taping a polite but strongly-worded note to the bin asking the thoughtless dog-owner to stop this habit and dispose of it in their own bin; it's worth a try. I suppose it's slightly better than dumping it on the ground, but still wrong.
