Should I expect the worst? (Vestibular Syndrome)?

You know that you have made the right decision and when to morrow comes you will pack the children off to school and ask the vet to come out to you and have you friend put down. it costs more but is the way he would like to go. When the children come home you tell them that he has gone and he is where ever you want him to be, garden crematorium. It's a tough decision but one that has to be made.
