Hi, I just have to say Maximus is so cute, he's a very handsome bully.
First I have a few questions, does Max have redness of the eye itself, ( like the whites of his eyes), or is it redness around the eyes ( like tear stains) ? Does he have any goop or discharge from his eyes? Redness and clear goop or a little yellowish can be caused by irritation of the eyes due to allergies and red eyes with a green discharge could be a sign of an infection of the eye like pink eye or other bacterial infection. An infection would require a diagnosis from the vet to determine what type of infection, and he would prescribe medication and or eye drops for this. If the red eyes are caused from allergies, then Benadryl can help alleviate symptoms, and you could also use over the counter eye drop from the Pharmacy ( you can use the same eye drops that you would use for yourself), buy eye drops that are for allergy symptoms, or even a saline based eye drop. If the redness is caused by tear stains, this can be caused by systemic reasons, such as allergies to food. Which brand of food are you currently feeding Max? Many bullies are allergic or sensitive to chicken and grains. It can also sometimes be caused by the drinking water, and can be remedied by using filtered water, or distilled water.
Having said all that there are some natural additives or supplements that you can give Max that will help with allergy systems and tear stains. I add 2 Tbsp's of p,ain yogurt to my guys morning kibble everyday. Yogurt is an excellent source of Probiotics which aid in digestion, and kill bad bacteria and parasites in the body, which helps to boost the immune system. (Allergies are caused by a abnormal reaction of the immune system)
I add 1 Tbsp of apple cider vinegar to their drinking water everyday. There are many health benefits of ACV. It is a natural anti inflammatory and ( 99% of all diseases including Arthritis, are caused by inflammation in the body), ACV kills the bad bacteria in the body, it is a natural anti fungal, and anti bacterial agent, so again will boost the immune system, and it also balances the Ph levels of the blood.
I also add 1 Tbsp of Coconut Oil to their evening kibble, this is a good source of Omega 3 Fatty Acids, which are great for the skin, coat, bones, joints and the brain. I buy my Coconut Oil from Costco, it comes in a big container, and is the consistency of lard.
