I have a 7 month old female puppy. She's had diarrhea/soft stool issues for about the past 4 months off and on. She's been on metronizadole and currently Tylan which both work like a charm. Her soft stool returns about a week after shes off Tylan but after a return visit to the vet he said hes never seen a puppy with diarrhea issues not work itself out with limited ingredient diet, time, and growth and that Tylan is a miracle medicine that works like a charm and doesn't hurt to keep dogs on just a small dose everyday (she gets 1/8-1/4 teaspoon every morning). My question is would allergy free, all natural etc etc Elk Antlers be a wise choice to give her? She's a very aggressive and destructive chewer and my neighbor has antlers and when shes over there she goes crazy over them. Thoughts on if these would be a good, safe, durable option?
