Feeling terrible about myself…

Since I had my baby, I feel like I hate my dog. He was everything to me and my husband before I had the baby but now I dont want him near me and I feel terrible for having that feeling. Have anyone gone through this? I haven’t told my husband yet about it, but I want to love my dog again. We are his only family. I am the one who take care of him every day. My husband travels for work to different states not always.
