@slowly This is a nasty habit, but not uncommon for some dogs. If he is eating his own poop-that is not as bad-but eating other's poop could give him some serious illnesses. I had a two year old rescue that ate his poop, when he came in the house after going out-(yard is fenced and sometimes they were out without me) I would smell his breath. If it smelled I would say "you ate poop?" and I would get a toothbrush and toothpaste and brush his teeth. Oddly enough, he (liked poop) but hated the toothpaste! After a couple of brushings, he never ate poop again. I would try to find a solution to discourage this. Sometimes it's just a stage they go through, There are things to feed them that is supposed to stop it, but I just brushed his teeth. Of course the bullies prob ably love toothpaste! Seems like they are not too discriminating about what they eat! Also all dogs love cat poop. Good luck and poop poop dee doop!!!
If you look on the net, there are many solutions to this,some work, some don't! Good luck.
