I'm Sorry to hear of your poor Maisie
I know how you feel, Well kinda, in 2006 in may my aunt died from cancer then in auguest my granddad pop died from cancer, 5 days after pop died my other grandad died from a stroke
As they say it takes time, Its been two years since they died and I still think of them everyday.
Hope you find another Dog such as your lovely Maisie
Don't cry for the sad times but cry for the happy times
like I do when I think of my Granddads and Aunt.
