Pumpkins are full of Vitamins A, C, Iron and Fiber and contain lots of Beta Carotene which is an essential antioxidant. The fiber can be very useful in the treatment and maintenance of digestive health of your dog. Few foods are more readily consumed than pumpkin puree (not the pumpkin pie filling) by our pets; just a small portion in their daily diets (1/4 teaspoon to 1 tablespoon, depending on the pet's weight) can make the difference between a case of chronic diarrhea or constipation and a normal daily bowel movement. Cinnamon is good for dogs weighed down with painful joints due to arthritis because its anti-inflammatory properties reduce the stiffness and help ease the pain associated with this musculoskeletal disorder. It is also good for the heart as its calcium and fiber content is effective in fighting heart diseases.
