Hi Louise,
I have a leather sofa (bought 6 years ago) wich the dogs go on all the time, we actually bought especially for them a long bench pouffee and this does have slightly more wear than the rest of the furniture, this now has a throw on for them to lay on. We did explain when we bought it that the dogs would go on it, and the salesman advise that we spend a little more for the leather that dosen't just have a coating on it, if that makes sense.
However this is not much use to you as I am in Gemany and bought this one here, I think if the dogs are on the furniture you do have to expect a bit of wear if you are not covering it with throws. The other option of course is to keep them off in the first instance, but if you are like me I can never resist the eyes giving me that look. :)
I have never bought a leather sofa from DFS, but have a fabric one from them, must be about 11 years old with removable washable covers (bought an extra set when bought it)
this is now in my bedroom for the dogs to sleep on and is in great nick, however I am looking at getting new covers made when we move next as they are worn now with the dogs using it.
To add I do clean my cream sofa approx every 2 days with leather cleaner, more often if the weather is bad, as the debris from their feet/ hair can also cause an abrasive effect on the leather.
HTH :)
