Hello Pip. In Jim's MMS Health Recovery Guidebook Chapter 15 Animals (a highly recommended read) it's explained that it's good to leave a time gap of 1,5 hours between the intake of MMS and food or medication. I'm not sure if the impact of the medication will be disturbed by MMS. It looks like an excellent way of making the dog or cat drink the remedy with bone broth, just enough to attract the appetite of the animal.

Friends of mine are going to try MMS for the treatment of their dog's fat bump. Since such a fat bump contains toxins, it's useless to operate upon it and remove it, for it will return. I'll share the results once I hear from them. I hope you'll have good results!.
