Sending you and Fred lots of love.
My last but one cocker, Rumpole, was diagnosed with liver cancer, the vet told me to go home and make a decision. Like Fred, Rumpole, was well, he had lost weight, but he was well, so I didn't make the final decision then and Rumpole lived for a further 18 months and he was happy right until the end.
So, if Rumpole had another 18 months after being given no time, if they have mentioned 1-2 years for Fred, I pray that it is the same ratio for Fred and he has many many more years.
