My mom is calling the vet right now. The thing is, she isn't acting sick. The vet thinks it might have been the stress of leaving her (we were on vacation) but that wasn't the case. She goes to the best dog sitter she could - she visits her dog mom, dad, and sister.

She is 4 years old.

She is up to date on all of her vaccines. The one thing that we didn't vaccinate her against was Giardia. (sp?) And we went swimming in a lake about 2 weeks ago.
