Again, thank you friends for your kindness and understanding. Am I crazy? Now I am terrified for Porsche. She is 13 and has survived mammary cancer. I can not stand the thought of losing her, too. How will I survive? Getting another dog will never replace either of these sweet ones of my heart. I have had her since she was 6 weeks old and only 8 oz. I keep her up to date with the vet. Again, am I crazy?
