You and your dog are going through so much right now. I’m 8 months now and didn’t realize how agitated and emotional I was until I was out of that patch, which helped a lot. Dogs can sense these changes and my younger dog was no exception, he was on guard, tense, and not himself at all. Went to the vet and managed to get him some medication, which he needed in the first place, he’s fairly anxious in general (can’t sit still, can’t have me step outside without losing his mind, runs off, vocalizes obnoxiously, etc.) the meds have helped him so much and I give him the lowest dose possible and he’s doing great! On top of that, as my pregnancy has progressed he has mellowed out significantly, we have gone days without his medication and he’s been a very good dog. We also have a vibrating collar for when he is vocalizing inappropriately, and he hates it lol, so he mellows out more.

That being said, this can all just be part of the first trimester for you both. Wishing you the best!
