My dogs eat poop, it is so disgusting. What can we do to get them to stop?

Hello,

I got my dog when she was about a month old and when she was about 4 months old we added a new dog to the family that was about a year old. When we got the older dog we found out that she was eating fresh poop in the backyard. She has now taught our young dog to eat poop as well. This is absolutely disgusting as they will come in the house smelling like poop. I am also concerned for their health. We have picked up the yard everyday and increased their food intake (thinking they may just be getting hungry) but these things have not worked. They do it when we think they know we are gone and no matter how much they eat, they still eat poop. We are getting to the point where we don't want them anywhere near us because of how disgusting this is. It's sad for me because I want to give them affection and they are also affectionate dogs but I cannot play with them for fear of getting poop all over me.

Please, any advice will help.

Thanks,
Aden
