My ex had two dogs - Kaiser the adorable and soft white Alsatian and Bess the totally bonkers Border Collie.
Kaiser had problems with his rear end for quite some time and passed away peacefully a week last Monday. On Saturday Bess was in pain from arthritis and had to be cared for by the vet unfortunately she had an adverse reaction to the drugs and suffered a heat attack yesterday morning.
Christine, Michael and Becky are bereft... the children had known both dogs since their late teens and to lose both in such a short space of time has floored them all.
It is hard to know what to say or do in such circumstances except be there for all of them.
