It is such a magical thing when pets seem to "sense" when their two-legged mommy is pregnant! My two dogs have been all about protecting the belly especially in the past month, I took a cute picture I wanted to share. Every time I lay down, within about 10 seconds there both dogs are curled up with the baby bump. How are your pets taking the pregnancy?

Pumpkin, bump security guard (several weeks ago when it was a far more subtle bump, lol)
Aw...that is so cute!! Our friends have a dog who seems to know I'm expecting...she usually is jumping all over us when visit, but now, she still jumps on hubby, but she'll just come over and sit right beside me and wants to follow me around the whole time. It's so sweet.
Mine (see siggy) hasn't really wanted to play with me for months now. She just wants to lay near me and saves her wild playtime urges for DH. I try, but she wants no part of it. She also sniffs my belly a lot.
My chihuahua does this too. I think she's going to be very jealous though. She does seem to stick near me constantly and has gotten much more anxious when I leave.
My lab seems to know that something is happening that is going to get more attention than her so she is mopey and gets very needy when DH is home.
My dogs have been around my son since he was really young and I was worried about that too but with each new stage of his life I just show a positive example of how to treat them. He loves them so much and he snuggles them like little ragdolls when he naps lol it's so precious. There have been times of course where he's grabbed a tail or gotten mad when they steal his snack, but I just try to be patient and show him how to be kind.
Hmmm... My boxer (almost 2) does the same thing. He'll play with me very minimally but loves to run and fetch with my husband. I am not 100% sure he knows what's going on yet, but some nights I wake up and he is curled up next to my belly. I'm not sure if it's because he knows he's got a brother in there or if he's just comfortable in that spot. Haha!
