Yep, that's all he is interested in these days. I am sure this has been discussed before, and I apologize for asking again.

Any suggestions other than me scolding him, because that sure isn't working?

Cat poop has a lot of protein in it, so it attracts dogs. To him, it's like finding treats on the ground. He will probably not ever be able to 'not eat' the cat poop unless you put it out of his reach.

I've never had experience with this personally, but I know how much dogs like cat poop, so good luck lol.

I'm sure others will chime in with their own experience.

My solution is baby gates and other means of blocking his access while still allowing the cats access.

We currently have a separate room for Sahara, it is gated with the walk through so I can feed her and such. Her food, water, and litter box is all in there. I had the same problem with Anna in the beginning so at first we used Anna's old wire crate. We cut a hole big enough for Sahara to get in and out and made it face the wall, so she had a little walkway and Anna couldn't bother her or stick her head through the hole.
