Wow, this is REALLY hard. I'm all over the map with this one.
My first thought, is I honestly can't imagine having my two small dogs back when I had newborns. I know for a fact they wouldn't have gotten the attention they do now. Yes, now THEY are my "babies". If we had another newbie right now, yikes..they'd be devastated, lol. We had a big dog (golden retriever) while we were having babies, and he was GREAT. But, as much as we loved him and cared for him...he was more of a dog. He didn't sleep in our bed, didn't sit on our laps. He wasn't NEAR as demanding for attention as these two little yappers are
I've seen so many pups end up at the shelter or advertised "free to good home", after babies arrive. Breaks my heart. Not saying that would happen to you, of course. Just that babies/kids turn a house upside down, even in families with the best of intentions.
Now, the other side of that. Maybe two dogs dealing with a new non fur sibling would handle the jealousy better if they had each other??
And not to be a negative..but I'd hate to see you hold off on getting another dog if that's what you want so bad. Because you have this plan of having a new baby in a yr. I'm VERY fortunate to have the four kids I have. But, I suffered yrs of infertility. I know there are other woman on this board that have as well. So, guess I'm saying realistically..as nice as a plan to have a baby in your arms by next April. It sadly doesn't always work out that way
Statistcly, it can take months..or yrs.
