I've been told many time that playing aggressive with them can make them bite. We play very hard which has at times caused me to get nipped or punctured by his canines, but he has never, never shown any thing at the vets. The techs know how to hold him and he is giving kisses while getting his shots!
Sure hate to see that on a record like that, but then again if there is a novice technician maybe it makes them a bit more aware of how they handle the baby. |
