Thanks for the replies and the welcome
I do remember that both needles seemed to have a pinkish colour which also worried me in the first place. I kind of feel really stupid and horrible right now because in the course of trying to do what was right I feel like I might have made things worse ugh. I'm not going back to that vet and I politely let them know that yesterday, so I'm worried about calling back and looking like a crazy person. There was another point we disagreed on and unfortunately she seemed unable to express her opinions in a professional and respectful manner. It all came down to her going to school for 9 years and so she must be right and at one point she even asked me if I knew what such and such word meant and when I said no she said, "I proved my point," or something along those lines. That's when I lost all respect for her is when she purposely tried to belittle me. Plus she gave my dog a very cursory examination, never asked any questions about elimination, eating, etc. She flat out said I was wasting my time and her time and my money by coming in.
