Hi Tom,
my sincere condolences mate.
Dogs really are man's best friend.
They know they are loved, and they return that love unconditionally.

Nearly lost my dog last week. Vet did a good job to save him.
12 years old 75% staffy and 25% Rhodesian ridgeback.
Looks like a staffy but the size of a large labradore.

Hang in there, and when it feels right, go get another one.

Regards

PK
