Thank you all for your helpful advice. I HATE waiting until Monday, but I am glad we could get her into a good vet. She turned her nose up at breakfast this morning and threw up twice, once about 30 minutes after waking up and another about 3 hours later. The first was digested food and the second looked more like straight liquid. She's been fine since, even trying to steal a french fry at lunch (I take her to work with me on Fridays).
For this weekend I am going feed her boiled chicken and potatoes. She doesn't do well with rice, so I am trying potatoes instead. Chicken is usually our go to when she needs a bland diet and she rarely has ever thrown up when eating it.
I am hoping it is allergies, but I want any tests done to rule out everything else. The more I think about it, the more I realize she licks her paws a lot, licks at her bottom and nibbles at it a lot, slides her face on the floor sometimes, etc. Right now her paws look like the skin underneath is red and it is pretty pink between the toes. A lot of the time it seems like it's after she licks her paws that she throws up. Could an allergy causing her paws to itch cause her to vomit if she is ingesting it?
Here's to hoping she keeps down the chicken and potatoes!
