We just got a precious little Westie pup two days ago. She doesnt chew her food and just today she started throwing up. She woke up this morning gaging but nothing coming out an hour after she ate she threw up but the food was still solid. She didnt chew it at all she did this twice today. Could this be because she is not chewing her food? I decided to add some water to it to make it softer and that seemed to help her some. any advice would be great.
