Hi, My puppy is 3 1/2 months old and started vomiting today after playing outside. He vomited twice but seemed to be ok after. It looked like everything he had eaten all day. He started nervously chewing on his toys about 30 min later then took a nap for an hour and ate a little food and then vomited again. Played for an hour slept an hour I then gave him a single treat and he vomited that shortly after. He played again and is now sleeping. Should I remove food for 24 hours? Do probiotics help?( this helps my horses)
