My Dachshund, a spayed female, 16 months old, is exhibiting a behavior that I wonder at. Our previous dog, a Labrador/Doberman mix, never did it, as far as we can recall (we had him his whole life, 17years.)
Most of the time, she keeps her mouth shut (barring tasting, biting, eating, etc.) But every once and a while, it's like she gets a dry mouth. She'll start smacking her lips, and licking them. It's not too much saliva, as she doesn't drool at all. We try to put her next to her water dishes, but most of the time she doesn't drink. She did this behavior again last night, and promptly up-chucked a nice pile.
We just had her at the vet, for an all day comprehensive check up and vaccination update. They didn't notice anything, so she either didn't do it, or they didn't think it was worth mentioning. (My wife dropped her off and picked her up, and I forgot to ask her to ask them.)
Does anyone know why she might be doing this? Or know if it is "normal" behavior in a very vertically-challenged dog?
