I suppose I've never really thought about it before!
So, as an intro: My dog is 9 and I've had him since he was 10 weeks old. He is my baby, I'm not going to lie, he is very spoilt and very attached to me. He does have mild separation anxiety but I've tried alot and it's now just to the point where he sits by the door watching/listening for me to return and doesn't really relax when I'm gone (he was ok before we moved house earlier in the year then he started to pace and bark and chew things so is alot better now, slowly getting there). He follows me everywhere when I am at home eg when I go to the toilet he follows me and sits outside!
There are no children in my immediate family and I have no friends with children yet so one has never been in our house. He must have seen toddlers and small children about on walks and a few older children have petted him over the years. But now I think about it he never would have really seen a baby?
I am now pregnant and wondering if there is anything I should be doing in preparation for when the baby arrives in terms of him possibly struggling with not being the centre of my undivided attention and also wondering what the heck this tiny screaming thing is in his house! He doesn't seem to have any clue that I am pregnant btw in terms of acting any differently (I thought maybe he would smell the change of hormones or something but obviously not!)
I know a new baby in the house can be difficult for dogs at the best of times and he did struggle for a long time before settling after we moved house so thanks for any advice on how best to prepare:).
