I just got the ruler out and had a quick measure. I can only say you would not want it on the end of your nose as a wart.
The UK KC does leave a bit to be desired when you compare it to many European KC's when it comes to hunting dogs. There are a lot of shows for hunting dogs in Sweden. Showing is part of getting your dog up to a hunting/ tracking champion. As i understand it there are not that many working Teckles in the UK and there are people who import quality working stock from main land Europe. Why put all that effort into keeping a high standard when anyone can breed teckles on just there own judgement. If i want a certain type of hunting dog then I'll research that breed and look into the best lines and breeders. I won't be going to someone who thinks he has a great working non pedigree dog. There are other things to look at besides working ability.
I had a English bred Springer spaniel that was the best spaniel I've ever had. A chap on the shoot wanted to use him as a stud dog but i refused because much as i loved that dog there was something wrong with him, something that you could not put your finger on but just knew. After a few years i heard that all his litter siblings had serious health issues.
Like most of what i write on here its just my opinion so me and my massive penis will leave it at that
