Composting dog poop with worms

This is a terrific website and full of great information. Reading all the questions and your answers helped answer some of my initial questions and was so helpful in helping me understand about composting dog poop with worms. One question that I still have in getting started is once I set up the bin and add the bedding, would it be best to add a mixture of dog poop and some other food to get things going, or ok to just start adding poop? And do you recommend adding just a small amount at first, or add the amount of food for the number of worms that I start with ( given the ratios that you discuss). Also, I couldn't tell from what I read about composting dog poop if you can just keep adding fresh poop, or do you also need to add fresh bedding along with poop sometimes. Is it ok for castings to continue to build up at the bottom of the bin until the worms and poop get close to the top, or should you harvest the castings sooner so it does not become toxic to the worms?
Thanks so much!!

Hello Maria,

thank you for your interesting contribution to our website.

Let me try to quickly answer your questions.

1.) You are welcome to add other foods together with your dog poop to the worm bin but it is not necessary if you don't have other organic materials.

I ran a worm farm purely on dog poop for years with the worms doing quite well.

2.) It is usually best to add new food sources in smaller quantities initially and increase the food (dog poop) with time as the worms get used to it. Generally, infant worms are adapting easier to new food sources than mature ones.

3. You can let the worm castings build up in your worm bin and only harvest it once your bin is nearly full. Nevertheless, it is not a bad idea to add a little bedding material from time to time which could help to add some safe places for worms in case the conditions in the bin have deteriorated for whatever reason. Some fibrous materials like shredded corrugated cardboard or crumpled-up sheets of an old newspaper can add some welcome pockets of oxygen inside the bin as well.

I am actually considering writing a propper downloadable manual about composting dog poop. Would that be something that would be of interest to you?

Dear Maria, I wish you a blessed day and lots of success with your dog poop composting project.

Once you got it going I am sure many dog-loving members of the worm composting community would love to get some updates about the progress of your dog poop worm bin. So it would be amazing if you could keep me and others informed about it.

Kind regards
