I took her to the vet for her checkup and she actually bared her teeth at the vet! Those who know Max know that this never, ever happens. She will grump, particularly when the kids get too close and too bouncy, but she has never even threatened to bite anyone. Now, at the time the vet was trying to check her teeth, and she and the tech had backed Max into a corner, and Max couldn't see me anymore, but still... It was a very unusual behavior. The vet said that it was like Max was a completely different dog than she was a year ago at her last exam.
Then our vet told me that I was kicking out a ton of pheromones ("Oh, excuse me!" I replied, and she laughed) because of the pregnancy, and that Max is probably reacting to the pheromones I'm exuding.
Since then I've been watching her more closely, and sure enough - this dog is being weird.
I just wondered if any of you had stories about your pets behaving strangely during your pregnancy.
