Thank you both for your advice. The option that I’ve tried, at the moment, is when we’ve had guests this past week, we've put both dogs in the utility room where they’re out the way. We get the guests in the lounge and sat down chatting, and then we’ve let them in to find the guests. All has gone really well as far as that’s concerned. Thank you. There’s still a situation when one of us turns up when they’ve been home alone but we’re trying to ignore them and hope the situation fizzles out. If not, then we’ve been splitting them apart and giving them time out (like children)! Not ideal and they’ve started first thing in the morning having a growl at each other as I’m trying to let them out. They are both trying to be pack leader but not all of the time. They’re such lovely dogs apart from this! They don’t fight/argue with any other dogs - just each other
