Can‘t really offer any advice but just wanted to throw in a bit of food for thought for thought..
I read a facinating book recently from Rupert Sheldrake „Dogs that know when their owners are coming home“ in which he analyses thousands of reports of animals, particularly dogs, who display signs of a sixth sense or telepathy. I know the notion is nothing new, some will pass it off as humbug, others are totally convinced, personally I‘m open to everything until its been totally disproved.
The question I‘d ask is, does Bailey have separation anxiety or just showing signs of anticipation?
I hope someone else might be able to offer some more constructive help, I just thought this might be an interesting topic for discusiion?
