Pet has not ate in 2 days

Question
I took my 1 year old Maltese to pet smart for a haircut they end up cutting her ear and leg and took they too they vet she was prescribed little whit pills called clavamox that I was told to put in her food once a day and an ointment called resotrin, ever since then she has been throwing up not eating her food and not her usual self which is playful and happy I stopped giving her the pills but she is still not eating any recommendations should I take her back to petsmart?

Answer
Oh Boy!  Sorry the Pets Mart messed up her coat and skin!
Call your vet and let them know she needs another antibiotic that is less harsh on her belly.  Also, I HOPE Pets Mart is paying for this!
Talk to the Manager and make sure that Pets Mart will cover this bill. This is not your fault that a Poor Groomer messed with your dog. Good Luck
