Hi Stephanie,
I own beside 4 american wolfdogs 2 czechoslovakian ones. And my female Myla Crying Wolf has a very strong personality. I trained her from 8 weeks on. I got her with 6 weeks. And with 5 month she would even be able to pass akc companion exam. So I can only recommand to train a dog as early as possible. But of course the hardest thing is to teach these strong characters to stay! Therefore this command must be done in real small steps. When your pup is 3,5 month, it is enough if he stays only for 10 seconds. You can increase this time of course. All other commands, you see it very well in Patrik his video, are easily done by a czechwolfdog. Never forget they are more german shepherds than wolfdogs!
My male, U´Tala z Molu Es, passed german VDH-Hundeführerschein - means dogsdriverlicence from similar like AKC here it is called VDH -. And I got him with 11 month from people who could not have him any more. On one hand he is like german shepherd and listens very fast to all commands and can be very hyperactic - like working class gsd - and on the other hand he is a real pet dog!
But it is much more easy to train a young dog than to wait til he is one year! Even speciality judges and absolutely breed specialist like Oscar Dora train their pups with 10 weeks with all sorts of command, which you saw in the video. I saw it 2 years ago with my own ice.
Helpful is always in the time where the pups grow to confirm with food, meat. With Clicker I am not experienced, but I do believe that this must work very well too. I know that Monty Sloan from wolfpark is training their wovles with clicker and he told me that it works very good.
But Saschia is right, if you have kids at home the most important thing is, to socialize your dog best possible! There is not a too much for a young dog!
