It largely depends on where you work it.
GSP’s generally show a lot of tail action.
On heather and open bog land you could be fine, lowland ground with hedges brambles and thorn bushes will definitely give you problems. Even docked dogs may get some damage
The damage normally occurs on the last third of the tail and even under ideal conditions takes a good long while to heal, it won’t get a chance to heal if you keep working the dog and when it does, the healed area is prone to getting damaged again.
You can easily have a dog out of action for a large chunk of the season.
Try it, if you get recurrent damage you may need to opt for an amputation, but not all dogs will need it.
