Dosages blueberry powder and barley grass juice powder: Our dog is Dobbie, 3 yrs old, miniture dachshund, female, not castrated. Her BEAM is good on all points. Currently about 10 days pregnant and weighing 6.8 kilos. She receives food that is a mixture of dry manufactured that is organic and homemade mashed potatoes and carrots mixed in with the dry food. Basis of dry food is lamb. I joined this site on the recommendation of Medical Medium. Anthony says he gives his dogs blueberries everyday and also said in his pets podcast that barley grass juice powder is really good for dogs. I am wondering about dosages? I chose to give our dog blueberry powder instead. Is that ok? I mix it with a little bit of banana. @Dr. Jeff
