How were they with other dogs afterwards? My 8 month old springer was attacked by a cocker today. He was very upset and ran screaming to me, but I can't see any sign of injury and he is happy now. The other owners muzzled their dog afterwards and told me he hated other dogs. I suggested they kept him muzzled while off lead, in that case!
This was Rico's first negative encounter with another dog. Normally he either plays if they want to, or has a quick sniff if they don't. He can happily ignore them too. In this case, he was just mooching about in bushes and the other dog ran to him. I'm sure he was just shocked rather than hurt, but wonder if this will affect how he is with other dogs. We didn't meet any more on our walk.
Sorry for the waffle!
