Personally I think wellness checks on chins in general do more harm then good. Unless the chin came from a bad situation (living in a dirty or rusty cage, fed a poor diet, etc or was abused) , or is acting sick or hurt I don't take them to the vet. There isn't much a vet can check for that you can't at home, make sure the eyes and ears are clean, the chin is a good weight, the fur looks good, no lumps, bumps or sores, etc . Most chins are stressed by going to the vet which can cause rapid heart rate and high blood pressure (so not a normal reading), as well as digestive issues, and stress can cause the chin to be more at risk of become sick since it weakens the immune system. So even if the chin was healthy when you brought it in, being exposed to sick animals in the waiting room it may become sick.
