I have a 10 week old puppy who is 4-4 on Asko. I do not have the knowledge to really talk about it the way others are..but I can tell you when I was making a decision I reached out privately to a lot of people that have owned or own direct progeny and some line breedings. (along with other dog's in the new pup's pedigree - I researched them all lol) Asko- he has a page on FB.."remembering Asko" or something like that for people who have his progeny. If you reach out privately to people you will usually get candid feedback. Most people who research and are into it seem to care more about giving a potential handler accurate information over ego..in private message.
Feedback ran all the way from "awesome dog" to "sold him" lol One man's awesome dog is another man's train wreck I suppose.
The feedback I got that was consistent whether it was a welcomed trait or unwelcomed trait (because different handlers want different dogs)- of the progeny ...not so nice of a dog socially. Some said it improved greatly with maturity and training, others reported a lifetime of social aggression. Some reported suspicion but liked it, some reported suspicion that was a pain to deal with due to low nerve threshold. Can work on the field but is a piece of work in other environments, stuff like that. Anything of that nature came from direct progeny 1st 2nd gen. And it was by far not all about that. PLENTY, had what they felt were fantastic well rounded confident dogs that they enjoyed working and having in the home.
Any feedback I got from people who had linebred dogs starting at 4-4 and farther back ..it was all over the place, no real consistency like with direct progeny, which didn't surprise me since over 4 generations so many other dams and dogs in there.
I stress, I am not qualified to give my own assessment on a pedigree..I am only sharing what I was told during my super extended and quite time consuming outreach.
How is my 4-4 Asko puppy? He is hard. I won't lie. He is only 10 weeks old so this is all evolving of course. He is a tough guy for sure. Very confident but not reckless. If something makes him unsure he sits, stares, then approaches it. Since he is not fully parvo vaxed yet I have observed this only in my yard, at a few friend's homes and yards, my front lawn with a dump truck going by while he was on a mini track I layed..and at the vets with other dogs struggling to get to each other. I am limiting free time access for training and bonding purposes with my grown dog..but when I do let them interact they like each other just fine. Again though..he is a new pup.
Landshark extreme, we are redirecting fools here. Food drive through the roof. I went out to take out the garbage this a.m and closed the gate behind me. He was crying and scratching because I though he wanted to be with me (awww). Nah. I opened the gate and he made a beeline to yesterday's mini track to see if there was magically food there lol Already kind of free heeling and sitting when i stop using luring and kibble. Will put his feet on a bowl..for food. Will work for food. Has great drive with biting rag/flirtpole. Have not done tugs or pillows yet. Another few weeks for that I think. He barks and makes eye contact to engage more tug with the rag. Very handler focused and lots of eye contact.
So all that is going great, but like I said he is hard. Had he gone to a pet home there would be people saying oh my God what did we bring home. It hurts when he bites you and he is relentless lol We are walking around with tug rags and little gappay balls, constantly. We are all wearing jeans and shoes while home which we normally do not do lol He does redirect if you have something..but, you better have something. He HATES being put in his crate. He screams for a minute or 5 then settles for a few hours. So that isn't so bad. We are dilligent about crate down time and how he spends his time outside of the crate. It isn't optional lol
I knew I signed up for this, I knew I wanted him, I knew what could be for the first 12 to 15 months. But I am willing to put the work in and have exactly what I expected both the awesome and the difficult. I know it will get a lot more difficult. He is SO FAR exactly what I wanted though and I am willing to ride it out and put in the work to make him the great dog his pedigree says he can be.
Flat out- most pet people would be really caught off guard and shocked with him lol There was also variety in his litter, someone mentioned you could expect that from your litter. The breeder placed his dogs..people communicated a lot with him and he told people about what dog will do what, can do what in his opinion etc. Mine was not the calm one lol
Edited to add- I see nearly every day a dog from this prior breeding. He is over 10 months old and a great dog. Excellent drives, mmm ok offswitch, nice social attitude. Can not get his attention off his handler when they are engaged but when he is "free" he is a friendly guy. 10 months and so far nobody has had to use the Quik Clot. Rest of that litter are very happy with their 10 month old dogs too. This was a HUGE factor in my going with this breeding despite a few hard dogs in there.
Anyway all that doesn't relate to you too much because the only thing in common would be the Asko linebreeding. Just wanted to share with you how it is going for me.
My other dog is a Czech/WGWL mix as well. But, I got him at 5.5 months and his temperament was a lot more unfolded than an 8 week old. He already displayed a good offswitch. His sire is/was a prolific Slovakian police dog. There are a few PPDs in his pedigree. He has defensive drive and suspicion. Not in a spooky way (for him at least, he seems to spook the people he is merely staring at lol). I needed training help with him but I am happy to say at 22 months old he is my right hand man, my rock. He is my children's protectors and can take a crying middle schooler on his big shoulder with the best of them. I have to watch him in public because if a stranger tries to greet him like they own him, he will back them off. However if they are appropriate so is he. As he gets older he is not as stranger aloof and suspicious as he use to be. He enjoys meeting people that are appropriate now. So I would say he is maturing nicely
His pedigree is in my siggy. So is the pup's.
Good luck, do your homework. Are you committed to this breeding? If others here have concerns about the dam's contribution to a male that is 4-4 on a obviously slightly controversial dog I'd be asking more in private (more likely to get direct answers that way other than vague stuff) . Research it on social media too. Like i said I found people to be candid on Messenger.
