I took my dog to the vet and Petco today. I gave her the cough medicine prescribed and fed her. She threw up everything she ate. I fed her again hours later which seems to be staying down but she seems to be behaving differently. She’s very tired now

Poor girl. This sounds like Dinero may be having a hypersenstivity reaction to the medication. Lethargy and vomiting are common symptoms of a medical allergy. She also could just be tired from her vomiting episode and just overall not feeling well. I would recommennd holding off on her next dose and contacting the vet who prescribed it to her in the morning for additional instructions on how to proceed with her care. There may be another medication that can be given as an alternative. Also depending on how lethargic she is and if she is able to bounce back after the medicine is out of her system, the vet may lower her dosage and have you try the medication again to see if this issue is repetitive. If she vomits again, it is best to hold off on food for at least 12 hrs before feeding again to allow her stomach to settle down. I hope that your pet Dinero feels better soon and is able to take her medication with no further problems! Best wishes and take care.
