Hmmm, it only happened once? It’s impossible to advise over the internet.
Depends on the severity of the symptoms.
So, if the episode caused you concern, at the least, a call to the vet would be best, even if it only results in a wait and see suggestion.
A veterinary health care professional would ask you the right questions and should be able to determine if this is something that needs immediate attention or not.
