I've just got back from walking in the fields with Sally. While i was there a nice elderly man shouted over to me to wash Sally's paws when we get home because the farmer puts 'lime' on that field and it'll burn her paws . Obviously I didn't realise this or I wouldn't have been on it. I was a good mile away from home so I started my way back and have just washed Sally's paws. Will they be ok? They seem ok but I've never heard of 'lime' what does this do? I wouldn't want to harm her.
