My dog is a chihuahua over a year old. I feed her Iams but she tends to get bored of it. She has spurts of straving for days. Is this normal? She looks like a concentration camp dog, I can see all of her back bones.

If I word it like this, does it sound problematic?

My dog is presenting anorexic spurts for days, is this normal?

Nope that little thing has well earned her self a trip to her vets office to visit with all the nice people. Where I suspect blood will be taken to help direct this condition and action to fix it.

Listen to the Doc.
