Tara, first thing you need to do is take a biiiig deep breath and calm down, crying twice a day is only upsetting you more, and Jade will be picking up on how you are feeling.
You have been very brave to post how you are feeling, good for you! Hopefully by now having read the other posts you are realising you're not the only one who feels like this. Sometimes it does take time to bond - you can't force it to happen NOW, it will happen when it happens - and it WILL happen!
I've been there with my old girl Ammy, when she came into my life 16 years ago whilst I loved her and cared for her, I always thought of her as my second dog. I had a silky boy that I was besotted with and I knew I felt different levels of love for both of them. I went through a period where I felt guilty, but eventually I just accepted it. She was still spoilt rotten, but like you the connection wasn't there. When my silky boy went to the bridge I was inconsolable for months, would break down into a sobbing heap at work, I never thought I would feel like that about a dog again.
The funny thing is I don't know when the connection happened, but it did, and I didn't recognise it properly until I was nursing my terminally ill mother. Ammy was there for both of us, she was my rock and kept me sane through the worst time of my life. I realised I had a very special little dog, and now I love her with all my heart. She won't be around much longer, and I am going to suffer dreadfully without her, no matter how much I prepare myself.
Tara, don't put too much pressure on yourself about how you feel about Jade, I suspect you will be like me, you won't realise the connection has happened until after it's happened!
