Dog acting strange 38 weeks

Blaire

I’ll be 38 weeks tomorrow, and since yesterday my usually very clingy dog has been acting very strange. She is fine when on walks and does her business outside but when we are inside she won’t look at me and shakes. She won’t come on the couch and snuggle with me like usual. She is only eating some of her meals. I just tried to give her a new tennis ball (her favorite) and she played for like a minute, then just stared at me like I was going to hurt her. She is normally my shadow!

Anyone have a dog experience like this?
