It’s pretty much been laid out in the show that he’s a bad “therapist”, mainly because he’s not an actual therapist, just a horse therapist. So I always get weirded out when people try to utilize what he talks about to analyze Bojack as a character. I thought the conversation about him drunkenly telling Bojack that he has a secret hatred for horses was meant to be a joke about how much of a hack he is, since it’s such a baseless assumption that it’s even proven wrong later in the series (when he visits the horse historical village place). He’s meant to satirize “therapists” who don’t have any more qualifications than an armchair, right?

Either way, I love it when shows do make therapy a flawed process. We did see an actually good therapist later in the series, and even then she slipped up now and then, and I felt Dr. Champ was supposed to be the antithesis to her. It makes the show feel even more grounded in reality, than therapists in other shows basically being the talking piece for the writers to roast their own character.
