They are both so adorable!! I wish you luck in finding them the best home. I know that having a baby and also owning fur kids can feel a little overwhelming....especially if this is your first baby. I felt this when I as pregnant, but thankfully, I didn't rehome mine. My children ADORE our dogs and I can't imagine not raising my kiddos with them....it's all they have ever known since we owned Harley before having our children.
I am sure that you have your own reasons for feeling like you need to rehome, I just wanted to give you a prescpective from another mommy.
Good luck with whatever you decide~
