Can anybody offer any advice on squeaking? Ihave a friend who has a very good young dog by saxaphone express 2 1/2 years to be exact, he is very well trained handles well, marks well and has impecable manners, he has been entered in scurries and done very well, more recently he has been entered in working tests but has been put out in the later stages for squeaking, this is something that has only recently developed, I have no experience of this so if anybody could offer any advice on the cause or the remedy, if there is one!! it would be much appriciated.
