I have had Luna now for almost 3 weeks, and i've been feeding her Science Diet for small breeds. She seemed fine on it, her poop is not too firm or too soft. Yesterday night, she stopped eating; I was a little concerned, but I figured she was just not really hungry. But, then this morning I saw a spot of vomit next to my bag; I didn't think anything of it and I left her food out (I never do this, but she didn't eat this morning as well), but my grandma just called me at work saying that Luna's vomiting.
I'm really concerned about what might be wrong, especially since this is my first dog. She has an appointment for a general checkup on Saturday morning. Any suggestions before then would be very helpful.
Thanks all
