I saw Simone today and found out a bit more. Ruby had a normal day on Friday – two walks, had her supper, had a poo outside then was on the sofa with the children and she just went. The vet has done a minor post mortem but couldn’t see anything for certain. She did think it was neueological and that Ruby died from a brain hemoreage (sorry can spell) and that it was like a light switch being turned off.
What is strange is Tia, their other dog, just went over and smelt Ruby and then since then has acted as normal, not pineing or looking for Ruby at all.
Simone is of course still in bits. I said about the Rainbow Bridge and posting on the forum that she had gone over and I hope it helps. Poor Ruby, God bless. :-*
