Beautiful.
I see so many photos here of Doberman with 3 collars and am curious about why that is.
Only speaking for Zastava and I, she wears a different collar or harness to be paired with a specific task. For nosework, that's a specific harness (she also has other harnesses, but only one is used for nosework practice or competition, and only paired with a specific leather lead) and when those two are connected, like today and yesterday, she earned Q's towards a new title, which she earned one in the last two days. Since those trials are sometimes in conflict with the conformation rings, we have to be ready to hook her on to her show chain and lead, lickety split. So that needs to be accessible very quickly as well, as judges dont expect to wait for you, and if they do wait, they expect you to look like you have worked to be as prepared as possible. Today she tried precision coursing as a fun run, tomorrow she has two trials in it, so she gets a new collar, one with a handle because i don't wanna risk my fingers when she is that pumped for a competition, and that collar will only be for that.
Katyusha, my golden child and therapy dog, also has a different collar to wear when she is on the job, although i have time to plan and change it early, so usually only one collar at a time for her, but i still change it out to get her in the mindset for the job. It seems to matter to the dog for mindset, so i do it because its simple and relatively cheap compared to therapy dog testing or the event fees i pay for Zastava to be doing these things she loves, so i do it.
I hope this all came across as educational and not snarky. Its just what we are doing for the weekend after having spent what we did and traveled this far to help her do the things that she is good at and also loves to do.
