Thank you for the reply. Kingdom has been on so many types and variations of food that Iām starting to wonder if itās allergy related not connected with food. We used to cook for him and here is an example of what we would feed him, cooked beef or turkey as the protein, add chicken liver from Whole Foods, add peas, carrots and broccoli add fresh sauerkraut and blueberries. I would also add hemp seeds and omega 3 oil and the stains would still be there. Another EB owner in my area told me it could be his saliva and it come from him drinking water and water dripping down his chin and it being wet that yeast is building up. If this is the case I donāt even know how to start to prevent this because itās impossible to wipe his chin/mouth every time he drink. Weāre not even around him a lot of the times when he drink his water because we keep fresh water out for her 24/7. Iāve tried every cream and wipe on Amazon and Chewy and nothing seems to help longterm. If this is possibly not a food allergy what steps do you recommend I can do outside of his food to fix this? If it is an overgrowth of yeast or bacteria on his body/paws at this point do I need a vets help or is there possibly something natural I can do? Someone mentioned apple cider vinegar. Wondering if any other EB owners with this issue has had success with this. Thanks again for any and all tips. Iām willing to try anything at this point.
