Too much saddle movement

[Jimmy260910]

Recently I've noticed that my horses saddle moves around a lot (mostly in the trot), its towards the rear of the saddle it seems to bounce on his back, obviously this isn't right. I was wondering if anyone knew if this might be something I could sort without paying for a saddler to come out? Or whether it's a sign that the saddle needs to be refitted?
many thanks

Obviously you need a saddler out - you are putting your horse's back at risk !

If it is bouncing on his back it needs looking at by a saddler, you can try extra padding but that is only delaying the inevitable and in the meantime it could be causing the horse to become sore which will need addressing with physio.
