Having been present at many castrations I would say it is a relatively easy op, it is more the anaesthetic risk.
Yup, this.
Benson is absolutely fine. He is only wearing the cone, as being a boy, it is very hard for him to leave his bits alone at the best of times!

He is having gentle calm walks to help him adjust to the change in hormones levels. Castrating Benson was an incredibly difficult decision, we did it for him so he could be more comfortable in his own skin, and less preoccupied with what other dogs are doing, both male and female. Some dogs manage very well being entire, and some don't, Benson is sadly one of the latter.
