Hi and welcome to the forum
So sorry to read about the loss of dear Jet; many of us have experienced similar heartbreak with the loss of our furry friends. I feel there is something particularly sad about losing a dog you've had from a pup

Jet has left you with wonderful memories no doubt, so enjoy them
Archie sounds great fun (cocker spaniels are my second favourite breed!) though I'm not sure we could cope with a particularly silly one

We have Toby, a lovely chocolate boy from the Rescue. He's a bit of an elderly statesman these days (10 next birthday) but an absolute pleasure.
Good luck with the second dog crusade xx
