Day One - Everything seemed OK

Our Vet examined Nathan, checked his back, checked his neck.  Nathan was already breathing normally again.  Just to be safe, Vet gave him an injection of an anti-inflammatory in his hind legs.  With that, we were off to the dog park.  Nathan played in his usual style.  After our designated hour at the park, we stopped by a street pet fair where the boys gathered up a fair amount of treats from the various vendors.  Nathan was his usual happy self.   By nightfall, he seemed a bit lethargic.   By 9:30pm, our last potty run, he was limping a bit, but we passed it off as a reaction to the shot earlier inthe day.   A few minutes later, we were all in bed, unaware of what the next 24 hours would bring.
