Aaaaaaaaaaarg. Grrrrrr. 
I was sitting with dh and dc in the park sharing a pizza between us which we had got from a nearby restaurant. Suddenly dh leaps up and grabs a dog that was about to jump on us whilst we were sat on the ground eating our food. He had to hold on to the dog until it's owner a stupid fuckwitt cunt woman came (about a minute later). The woman made no serious attempt to call her blood pet (massive in size, some sort of mutt). She just meekly called whispered "emmieeeeee, eeeeeeemmiee" but unsurprisingly stupid dog didn't listen to fuckwitt woman at all.
She then proceeded to tell us the classic line "he's harmless" to which I responded "well I still don't want him jumping on me, the dc or our food.
She had the bloody cheek to answer back "the park is for everyone and that we should get used to dogs". I said "sure, i'lm used to dogs but still don't want one humping me, the baby or slobbering my food".
She went on to say some more tosh and I warned her that I would call the police as it was clear that she couldn't control her bloody dog.
She went off in a huff but not without lecturing me that I should not be rude to her in front of the dc.
Seriously, how can some dog owners be sooooooo blooooody stupid? I don't get it. I love dogs, hope to have our own dog one day but I will make damn sure to train the dog and not allow it to bother other people.
