Since I got Nicole she hasn't been very interested in eating or drinking, in fact she's only been eating less for every day. Last night she threw up a little bile, and now she did it again tonight. I'm feeding her ~0.6dl dry food at 6am, 4pm and 10pm (hope I didn't get the pm's and am's confused). The throwing up has been happening around 2am-4am. She's getting the same food that the breeder gave, which is Royal Canine Mini Junior. She also smells somewhat and I've looked into her ears trying to see if there's something there, but it was clean, so I assume it's coming from her mouth.
Should I go see a vet?
