Foster vs Adoption

I know at some point in your life, we'll want to share with you about our experiences and I thought this might be the best way to remember them.  I heard a story recently about a friend we know who was adopted at 18 mths old and he was always thankful for his adoptive parents and really wants to give back by adopting children some day as well.  That would be so beautiful to raise children with a heart like his, so in case that happens, I think it would be great to let you know what things might have crossed our minds along the way in all the decisions that must be made throughout the process. 

One topic right now is Foster vs Adoption because our dog Sadie was just diagnosed with Lymphomic Cancer, so it spreads very quickly throughout her entire body and we were told she only has a couple months to live.  This dog has been my child for the last 5 years of our marriage, I take her with me everywhere I go and have cried many times if there is a time where I have to leave her for an extended period (because of work usually) and I can't handle looking at her eyes when I do go.  She is my child and I love her soooooooooooo much, so with this sad news, I am heart-broken.  So it has brought me again to the question of whether I would be able to handle Fostering since I would get my heart broken over and over and over again possibly, when I am supposed to just be a care-taker of these precious children and I don't want to let them go.  When we last met with the social worker, she talked about a couple sibling sets that were at the top of our "preferred age range," but were ready to be adopted...so I am praying about these children and am knowing that God has the right situation being worked out for all of us and I have no idea what is in store in our lives in the "hopefully VERY near future:)"

The Lord giveth and the Lord taketh away.  I have Faith that he is working my situation out for the good!
I love You Lord
And I lift my voice
To worship You oh my soul rejoice
Take joy my King in what you hear
May it be a sweet sweet sound in Your ear
