Dexie is 16 months old. Sunday night he started making gagging sounds but never threw up,monday morning i took him to the vet after he had trouble eating without making those horrible sounds.Vet said it could be reverse sneezing from his sinuses and gave him antibiotics.It is now tuesday but he seems lifeless and does not eat well though the sounds are much less,now he sounds like he has got a cold. but it worries me that he is not himself. I am freaking out and can not afford another consultation right now.What do you think?
