Thank you for the advice. She is booked in with the vet tomorrow afternoon. Berry has a long history and there have been three occasions where she has lost a mate. My family bought her as a present for my dad for his 60th birthday. The two of them were best mates for a year and then dad passed away suddenly. She went into a depression. Five years after that, she and one of my beagles got out, I found the beagle, he had been run over by a road train and my husband literally had to scoop him up off the road to bring him home to bury. We found Berry the day after, filthy and shaking way out in the sticks. My last beagle Brody passed away at the start of the year after being diagnosed with cancer on August last year. I am really feeling for the old girl and I have a pretty strong expectation that the vet is going to say that she is just a nervous/anxious dog.
I have just bought an Adaptil collar at your suggestion. Anything is worth a try right!!
