Just wanted to update and let you know that we have been lucky enough to find a companion for Chino. Her name is Bella, a 6yo Collie/Lab mix. Needed rehoming as the previous owner was unable to give her the attention and care she deserves, to the point where his family stepped in and removed her.
The PO's family brought her to us (from Worcs) on Saturday as they (understandably) wanted to site visit and meet us. It has been incredible how quickly she has been accepted and accepting of our family. This weekend was 'full on' due to the 60th, so plenty of new people, locations and situations (and dogs). She handled it all with ease.
Obedient, gentle, well trained, and great around other dogs, we have really fallen on our feet with her. Chino's a bit put out having been an only child for 6 years, but i think she likes the company, which was the reason for having another dog.
