Brought my new yorkie puppy in 2 times in one week because something was seriously wrong with her energy level and she had runny stool. Both times the vet said she was OK and it was normal. Turns out she had a parasite and had to be taken to the hospital for 7 days. Things wouldn't have gotten so bad if they diagnosed her sooner. When asked why a red flag wasn't raised the first time I came in with concerns the vet answered she wasn't used to small puppys this size. Unacceptable answer.
