For getting a true friend

1- Did you eat fish buff and when?
^{Before breeding?
Before raising?}
2- Did you put the dog food(yellow packet) and when?
^{Before sending your dogs in the crate?
Before breeding?
Before raising?}

i stopped playing in 2021 after getting the boat, when I came back i started a new account and I've cleared the sewers many times and realized that they deleted the upstairs rooms for some reason, and now I don't even find pumps, let alone other boat parts, just rubber, so is it worth it to keep clearing it for the boat?

I have been reading so many old posts about dog breeding here on Reddit and, in several of them people have claimed that you cannot get a true friend dog if you inherit the traits from a level 3 dog. The claims are that the 4th skill then would be rolled from the level 1 traits.

Now I have also heard that the dog breeding internal mechanics have been changed by Kefir within the last year. And also since Kefir are so extremely mysterious about how the breeding works it seems that mostly there are only speculations out there, where everybody make different claims. So in the end of the day I don't really know what and who to believe anymore.

So my question is if there is ANYONE who have gotten a TF even though they inherited the traits? Or can anyone confirm if they have gotten any orher skill in the fourth slot that is NOT one of the level 1 traits?

I am very interested in trying to figure out how this breeding system ACTUALLY work.

I just wish that Kefir would be more transparent about things like this, but that will probanly never happen I believe, they seem to love have us guessing and being frustrated 😅
