DH and I went to sell some junk unwanted items at a car boot sale today. We took DD (21 months) with us for the first hour then my DF came to collect her.
The car boot was in a field and when we arrived it was already very busy with both sellers and buyers. Many people wandering around had dogs with them on leads.
I bought DD a sausage sandwich and popped it on the table near her pushchair to cool down and gave her some of the bread to munch on.
A pig ignorant woman walked past my stall with her large dog off it's lead. The dog ran around to the sandwich and bit it, scaring poor DD senseless in the process.
DD was screaming like mad. I got in between the dog and DD and shouted at it to get away. The woman was stood at the next stall laughing! I shouted to her to put her dog on a lead and she just laughed again and walked off. No apology, didn't offer to replace the sandwich and didn't bother to check DD was ok. 
DD ended up eating my sandwich
as the queue was too long to wait for another again.
DD has been scared by a large dog before and I've been trying to gradually introduce her to dogs to get her over her fear. Now she's been set back again 
I've nothing against dogs or dog owners. Just a small percentage really annoy me with their attitude. If the sandwich had been in DDs hand the dog could have easily bitten her getting it off her 
And breathe. Rant over.
