Hi Helen,
I've got 2 older corgis and I dread the day when I lose them. My oldest one, Zoe (will turn 14 on Sunday) has suffered ruptured disks but luckily is still able to get around on her own and is full of life.
They also have two aussie 'sister'. The aussies seem a lot like corgis to me only with legs.
I love the two breeds.
I hope that a corgi will join your household again someday soon.
