We have a 7 year old female greyhound. She was diagnosed with osteosarcoma last summer, had a leg amputated and a course of chemotherapy. She did well throughout all that, but during chemo she had trouble with her white blood cell counts, so the oncologist had her on a couple courses of antibiotics and prednisone. She's currently on a very long, slow taper down of the prednisone but no longer on antibiotics.

About two months ago she started coprophagia.... never did that before. We've been doing everything we can to stop that:

• Supervising her in the yard and saying NO when she starts to eat a pile, rewarding when she comes away from it
• cleaning the yard every day
• changed her food
• added coprophagia supplement to her food and our other greyhound's food (stuff that makes their poop taste bad)

It's been a struggle, to get this behavior stopped. (There are still some times when we let her out unsupervised.) This morning I was googling for more ideas and I saw an article from the AKC that listed all the possible causes for it and one of them was the dog being on steroids. Ah... so it's the prednisone that's likely making her do this. She's going to be on it for a few more months still, based on how slowly we're tapering her off of it. So my question here is, do we just keep going like we are with the above until she's done with the prednisone taper? Or is there something else we can try?
