Sometimes things just don't work out

This morning I tried to walk Java and Genny together and as soon as I put Genny on the ground, she and Java went at it. It was scary and horrible. I tried to separate them, but my hold on their leashes wasn't close enough. I tried with my foot and they went around me. I finally picked up Genny, who had Java in her mouth, only to have Genny drop Java, who fell onto her back. It was terrible. In my horror, I called the foster coordinator who said she'd take her for me. I feel like such a failure, even though it's a dog thing and not something I did. This was destined to be the outcome at any rate, she was not a dog I was planning on keeping, so I have to tell myself that it's not my fault and maybe I'll feel better if next time I have a success.
