I am just now seeing this. I am so very sorry for your lost of Cherry. I know she was very, very special to you. She was a beautiful girl. I had a similar experience with my first maltese pup about 7 months ago. I know how you feel. Life goes on whether we like it or not. In time things will get better but I know, you'll never truly get over it. I don't think anybody will ever get over the death of a loved one, especially an animal. But life goes on...and they'll never be forgotten. 
Did you contact the breeder? I know you've had problems with her in the past and she's all the way in Canada, but did you have a health contract? If it was a heart problem then that is most likely hereditary, therefore, it is not your fault, but the breeders.  
Please PM me if you need anything. *hugs*     |
