Once yesterday and twice today Charlee has thrown up his food. I just had him at the vet on Thursday and he checked out fine. Then Friday I was walking him at the park and his poop had worms. I took him right over to the vet and they gave him Pyrantel in a syringe and gave me another to give him in 2 weeks. Do you think the throwing up could be from the worms or medication? His poop is fine now and he's as active as ever. I was thinking maybe he's eating too fast but since the worm incident, I'm worried.
