Hi LucyThanks Eve - I know I should keep waiting - its been nearly a month now but is still very raw, I guess I hope that at least the search will take the edge of it.
I am also hoping that there might be a pup from a litter being bred from a half brother of my girl might be a possibility, but that won't be til Xmas ......and I'd quite like two anyway!
It was about a month after Peat died that I took on Toddy. Peat had to be PTS 1 week before my 2 week holiday in Central America, I then found Toddy about a week later. It was only about 5 weeks in all. Definately not enough time. Keep looking by all means but give yourself a bit more time. A month is not really enough unless the dog you are taking on is in desperate need like Toddy was.
A close relative of your lovely girl may be the way to go but you may have the same problem as you do with colour, too many memories.
Christmas is only 11 weeks away tho'
There are sometimes whippets needing rehomed together on ePupz.
Sarah (whippetwise on k9) Whippet rescue Ireland may be able to help http://www.whippetrescueireland.com/ They will transport whippets and greyhounds to new homes in the UK. She gets in quite a few whippets.
Best of Luck
Eve
