We all like a good discussion so how about this one? What age should a Glen of Imaal Terrier dog be first used at stud? The US Code of Ethics says not until all health tests are done and that is around two years of age. In the UK a “young” litter has always been the norm for prospective stud dogs so it can be seen how the resulting pups develop and, more importantly in a country that doesn’t consider artificial insemination anything like the normal way to go, it gets males used to being handled before maturity begins to click in.
Think about it
