Super answer, Seafarer. Really, so helpful. a**e...
Hi itsgary, not sure what to suggest...Are you present whenever she poos? If so, you could try sprinkling pepper on her poo before she goes to eat it, and on the cat's poo too. This should put her off! I have also heard that a wee bit of pineapple added to your dog's dinner makes their poo taste bad (I don't know who researched that!)
There are other ideas, and I am sure someone will post more comprehensively for you. Good luck :) A cuddle for your dog too.
