Sorry to hear you're having this challenge with your pup, Kathy. As with any behavior, coprophagia (consumption of feces) responds best from a combination of behavior modification (yours and pup's) and supportive therapies, such as additives to change the taste. It's good that you're addressing this at 6 months, because In my experience, this is a particularly challenging behavior to eliminate. Not only is it pretty easy for most dogs to find other dog's excrement on a regular basis, many learn to eat the supposedly offensive additive (pumpkin, in this case). Every time your dog "wins" sets your training back, so this step is crucial. If you want to minimize your frustration and teach your pup what you want, you need a plan that includes managing what he has access to, teaching him specifically what it is you want, and being prepared to reward/reinforce for at least 3 months before you relax the rules, so to speak. A competent dog behavior professional can help you establish a plan, and provide coaching for both you and your dog, to help you reach your goals. You can search for someone in your area at: http://www.canineprofessionals.org There's a LOT of information about coprophagia on the web, so you can learn a great deal through research. Wishing you the best of luck.
