Am I a horrible person?

Jessica • Just married, next on the check list... Babies!!
I had a missed miscarriage on 10/07 where the doctor told us my 8 week baby stopped growing at 7 weeks. We'd like to try again as soon as I stop bleeding which seems to finally be soon. So here's my dilemma, my husband has a 18 month dog who is very very high engery and causes me lots of stress (we live in an apartment). He needs so much attention and when I was pregnant he had several accidents in the house and one time I even had to carry all 75 pounds into the bath. Not to mention I really disliked him while pregnant. Now I know he didn't cause the miscarriage but I can't help but feel angry towards the dog. I asked my husband if we get pregnant again to send the dog to stay temporarily with a dog sitter. He agreed but I know he's really sad. The other day I said  "I can't wait to start trying again" and he's said "maybe we should wait". I got my such a sick feeling in my stomach and I can't help but think maybe it's because of our agreement to send the dog temporarily.  I feel like starting a family is more important and I feel like he wants the dog to stay. What are some of your thoughts on the situation? Am I being a total 'B' by making him send his dog away?
