oh god thats really annoying!!

we have a cherry red leather couch and before we bought it we had a cream material of some sort couch that pur dogs were allowed to sit on coz it was old and cruddy.

when we got the new couch our boxer just liked to sniff the couch and NEVER even attempted to sit on the couch, my jack russell on the other hand would be jumping up and down all the time, we just kept on her back teeling her off when she did it.

admittedly our dogs sleep in the laundry at night do they cant access the couch.

but if we go out and its raining they stay inside and therefore would sit on the couch so we got a old blanket and they learnt if the blanket was on the couch they were allowed up.

but a few times when they have had major brain farts they have jumped up and marked the leather. its not to bad but its bloody annoying, we just put the leather cleaner on it and it seems to dull the marks down.

im freaking out they will rip the red leather one day though...

good luck!

oh and we use leather cleaner for cars, works a tone better!
