I use Infusium 23 on Mario, but not for tangles since his hair is mainly short/med. I use it for sheen, and added softness since he is a tiny bit wiry without it.
If you google, you will find show competitors use infusium 23 on their show dogs too (

I have used the Infusium 23 on my kiddo for tangles for over a decade, and it works great.
