Thai had blood work taken- his medication might be changed, depending upon what the tests say and we don't get the results back until Monday.
The yelping is due to his back. The vet advised keeping him on two Tramadol a day or going the surgical route, which could be deadly due to his age and also the possibility of a blood clot.
Since he is still pretty active and only the yelping is new, he is still in pretty good shape.
Thai is again guarding the kitchen, and is showing less interest in people food again today. Also would not eat his treats for going outside!
