hi,could anyone tell me if i have a problem or if its likely to become one?my 6mths collie bitch pup gets on fine with lots of dogs(collie sized and below)but is wary of larger dogs.if we meet one in the woods,she lrun off in panic,but if she sees me talking to the owner,she lcome back,get brave,and start "play"snapping at the dogs jaw.i correct her,and fortunatly,the dogs have all been benign about it,but id appreciate any thoughts or advice!

i don't know about collies but it sounds as though your dog is unsure of bigger dogs and therefore responds in the wrong way.
i would try putting her on the lead if you see a dog that maybe a problem and getting her to sit and be calm, giving treats for the right behaviour but keep everything low key and don't let the dog think your stressed.

thanks,il try that!im on holiday in newquay this week,and the problem just escalated,!she snapped at a friendky medium sized dog,and then a jack russell,one on lead,one both off,she didnt seem particularly worried,either!help!
