Think you may have solved your own problem!!!!
Tessa Evie may well be soiling through the night because she is getting stressed on her own, and as you said she is not a barky dog so rather than vocally complaining she may be silently working herself up into a stressful state and that's why she is being dirty. Keep the Rescue remedy up for a day or so. As for fireworks Solo was one of my keenest workers and never minded a shotgun going off, but Fireworks terrified him, I think it's such a repetitive sound that is higher pitched it does freak some dogs out.
Tor, Andy should be proud, but it does help to have a handsome subject !!! ;-) Am I having Ludo for your honeymoon I can't remember what if anything we had arranged?
Hello honey! Diva is very please HER Pete is on the blog, last week when Peter came to cuddle, (puppies of course) Diva was very possessive over him, she sat on his lap blocking vision between Peter and anything/one else and when Summer came in, Diva who never growls decided to growl at Summer every time she went near him!!! What a Tart, (Diva not Peter!!!!!) Diva only has eyes for Peter when he is around, even more than Judith!
