1 month (not planned) but our younger dog was terrible when the old springer died and laid on his grave in the garden pining most of the time. Made my grieving process ten times harder too. Called up a breeder to ask about their next litter (was planning 6 months ahead) to be told she had an unwanted choc lab available there and then. Bit shocked but went with it and was the best thing we did all-round.
My old boy Barney. He taught me everything about dogs and was very patient with me as a beginner. Miss him terribly.
