Thank you for your question. My name isXXXXX and I am happy to be able to help you today. This definitely seems very interesting with little Brody and while there are a couple of possible causes for Brody's episodes yesterday - this is most likely a syncopal episode from what you have described.
If Brody seemed to collapse all of a sudden, but then recover just as quickly then this is likely syncope - aka fainting. It definitely doesn't sound like a seizure like episode if Brody wasn't shaking, didn't urinate or defecate during the event and recovered quickly. Syncope can be caused by a number of different things, but in this case, it could just be that during the vomiting/choking episode during the walk yesterday, Brody wasn't able to get enough oxygen to his brain
. If he was choking for more than a few seconds, then this could have been enough for him to faint due to a lack of oxygen to the brain. This would be the most likely answer as to why this happened.
In saying that however, you should keep a close eye
on him. If this happens again, then you will need to get Brody carefully examined by your local Vet. Here they can have a careful listen to his chest to ensure he doesn't have any primary heart issues. Young dogs can have congenital heart problems that pop up at around 6 - 12 months of age, so do be sure to get him checked if these symptoms continue.
