Strange dog behavior... anyone have experience w/ this?

[texas*princess]

About a month ago I was traveling like crazy... maybe 4 days a week, come home for a few days and take off again. I normally don't travel that much but all the trips just kind of fell together.

I noticed when things got back to normal and I was home all week, my dog was eating less and less. For a while, I thought she was going on a hunger strike in protest of me being gone. She normally ate dry food.

That food that she was eating was kind of bland - made for dogs with sensitive stomachs, and since she was having issues at the time, that was the food she had. So I thought maybe it was just the food. I went out and bought a different kind, supposedly healthy & they said "dogs love the taste" so I decided to give it a whirl.

She will very rarely eat it if it's just plain dry food by itself. Sometimes when I mix in a little bit of wet food, she will gobble the whole bowl up.. other times she will eat all the wet food, and eat part of the dry food. But even now she will barely touch her food if it's just dry food.

I've taken her to the vet and they checked her all out and found nothing wrong.

Is this normal??? Should I get a second opinion? I just find it odd because she was always a quick eater.

She still "asks" for treats, so I'm assuming she's hungry, but I normally won't give her a treat unless she earned it. And i won't give her treats that will spoil her dinner.

I don't want to resort to feeding her only wet food because I've heard it's not great for their teeth, but I know that's something she'll eat... so is she just being picky? Her energy level is the same, so I don't know what to do with her.
