Definately talk to your trainer/instructor about those incidents and your concerns . Maybe she saw something different than what you did or maybe she missed it all together . She definately needs a heads up, a dog taking off across the ring to harress another is not acceptable.
Regardless of the snarling dogs intentions ,it's not fair that your dog was subjected to such behaviour .
Kudos to Fran for not reacting to the other dog. Many dogs aren't so tolerant of being approached by a snapping, snarling dog and will become aggressive in response.
Simular behaviour at a trial is open to interpretation . If viewed as aggression , the dog could be banned from that trial or may even be banned for life from competing in that venue ( AKC , NADAC , etc.)
I agree with hokisteph5 , definately use a nice loud clear voice " call your dog " or " control your dog please " for future incidents ( hopefully there won't be any ).
I've done this several times when seeing a dog heading towards Henry in a less than friendly way. Amazing how much faster handlers respond to doing something about their dog when it's loudly been brought to everyones attention that they may not be on their best behaviour
