This happend for the second time now and I'm wondering what it is. My boys have recently been to the vet, and the one that was sick is doing 100% better now. The other one was healthy and happy. But last week he made this kind of coughing sound when I fed them their dinner. It sounded like he was choking on something, so I ran over to see and he just looked up at me like I had the problem lol. He hasn't done it since until just a little while ago. I just gave them some romaine and he was eating away and he made the choking sound like two times. But he looked perfectly normal, didn't seem to have a problem, just kept on eating. He's stopped making the noise, but I was wondering if anyone could tell me what this is?
