What is your greatest pet peeve with OTHER dog owners?

ya I hate the ones you mentioned too. However, being a volunteer at my local shelter has give me a whole list of new hates. A number one is breeding their dogs. 5 million unwanted dogs and cats are euthanized every year in this country. number two is abusing their dogs. Starving, striking, burning, fighting and totally abandoning them and moving away. 4 is leaving them in yards or in the hands of someone who can't handle them while on vacation which leads to them getting out, run over, or into the shelter. 5th would be inadequate training. Take a good obedience cl for heaven sakes!
