I know this is not the intent of @Quincy 's thread and we are getting off topic, but I want to tell it!
Yeah Ruth, Betts just loves guests because, guests mean food treats and pats. She's totally non-judgmental, she accepts every human as a new friend. She sits at the front gate and waits for the next guests to arrive......

But because of her welcoming bark I need to forewarn incoming guests that she will go into alarm mode as soon as she hears a car door shut out the front.
But some guests are afraid of dogs and are hesitant on arriving so, I have to give them good warning on my listing page and welcome message.
The thing about a dog that an electronic device can never do.....they are adaptive, they asses situations, sometimes with amazing consequences.
We had a one week booking from Nick and Hannah from London back in 2016. In his booking message he said his only reservation was, Hannah had been bitten by a dog as a youngster and had a life long canine fear. I told him I had a family member living 1.5 Kms away from here, I was quite happy to take Betts over there for the week but, Nick said, "Well lets see how we go", he explained the situation to Hannah and they were prepared to 'test the water' as it were.
The strangest thing happened Ruth....when Nick and Hannah arrived Betts just sat at the back door, wagged her tail but did not make a sound and did not rush to greet them as she would other guests!
What sort of sense do animals have that enables them to do something like that?
On the third afternoon of their stay we were all sitting around an outside table and Betts came up and just sat between Hannah and Ade, just sat there. After a while Hannah pushed a biscuit across and off the table which Betts gobbled up, that was it, nothing further.
On Thursday afternoon Hannah asked if she could come out with me while I threw the ball for Betts to retrieve as I do every afternoon. Hannah threw the ball a few times and Betts bought it back to her feet each time.....a definite bond was forming.
When they left on Saturday Hannah gave Betts a pat and said her personal goodbye to Betts.
Here was the review that Nick left for their stay........

This dog is a solution to every problem....
She is a faithful companion.
She is an intruder alarm.
She creates affection.
And she is a wonderful psychologist.
Cheers........Rob
