She’s never had this problem before surgery. She never threw up after eating. Always chewed her food even if she was eating quick. She was being syringe fed at the hospital and I also did a few days after hospital. So when I feed her the smashed wet food she’s fine once I give her chicken or thicker food even wet that needs to be chewed first, she won’t chew just swallow seconds later she does what looks like reverse sneezing and throws it out with white foam along with it. And sometimes she’ll make weird noises also after. But minutes later she’s up barking running and being very normal. Please help what can I do or what can it be from?
