Did anyone’s pets starting acting weird before you knew you were pregnant? My maltipoo has always been very well behaved and just recently he started acting out. He started getting into the trash can, chewing random things up, and not behaving normally. We just finished a round of letrazole and we’re just waiting to see if it worked, but my veterinarian gave me the idea of maybe he senses it and is acting out. Thank you for taking the time to read this post.
