I asked about having blood work done and he said to watch him and see if it happens again. Other than this one episode Ritz has been extremely healthy and acting normal. I work from home so I'm with him all day and night and haven't witnessed anything besides this one episode.
He had been playing with my friend for a while right before this happened which causes our vet to think it was low sugar level.
We are 110% willing to get whatever tests done that Ritz needs.
Thank you everyone for your responses
