my dog is turning 6 years old on the 21st, he is a mini pin mixed with a chi. every so often he will get a reverse sneeze but not often at all and I have not heard him do it in a while. but the other day I was gone at my sisters for a few hours, and he was home alone with my german shepherd, and my lab. and when I got back he started reverse sneezing and shaking. I did not know what was wrong but did my very best to calm him down! my german shepherd sometimes trys to play with him but sometimes gets too rough. he gets kinda scared of that sometimes but I don't think that's it. so know he was just doing it again, it scares me, and I can tell it scares him when he does it!! so I always try and calm him down and make him fill safe. but why is he doing it so much lately? is it cuz he wants to be with me, or is it allergies. he has never had allergies before. is there anything I can do to help him!?View attachment 1935680
