Should think not! Why would anyone want to do that? The poor dogs made to sit there with a stream of ( very polite and courteous) runners coming at them. I'm sure no one with an ounce of care for their pet would do something so selfish. Like I said, it was a crazy thought, sure it wasn't their intention to behave so. Perhaps they were standing in the centre of the path side by side because they were overwhelmed at the incredible site of such a successful event? I did see many happy pooches enjoying the run/ walk with their owners which was lovely. One of the first runners back was a happy little pup.
