This will be a very very long post, I found something I read some time ago, this diet is recommended by a lady called Linda Arnt, she is a canine nutritional consultant. She is great with large to giant breeds. It sounds like a lot of info. but I really would try it in your situation. Hold on here goes:
Feed a super premium kibble she recomends Eagle Pack, I use that on my mastiffs and am super pleased, you can see where your nearest rep. is on their website
www.eaglepack. comThen she says you want to give dietary enzymes, which she says is missing in all kibbles, Nzymes that produce antioxidants to flush the toxins and byproducts from the dying yeast/fungus out of the body (those things are one of the reason the dogs get sick) the Nzymes can be ordered online
www.nzymes.comThen she says to add a digestive enzyme - probiotics. It is a friendly bacteria like in yogurt, but yogurt is not enough for a situation like this. She suggests BakPakPlus - fortified, I believe you can order that on
www.nzymes.com too.
Vitamin C - 1000 mg of vitamin C for puppies 12 weeks and up to adult dogs (if you use EsterC 500 mg = 1000 mg regular)
She also says to add a joint support supplement
Also add Oxidrops, to alter the PH of the gut so yeast does not like to grow, can also be ordered from
www.nzymes.comTincture of Blackleaf, to kill the yeast, I am not totally sure, but I think the same website goes for this too.
Then she wants to add canned meats or raw/cooked meats, she recommends the Eagle Holistic canned dog food 3 tbs - 1/3 can, she also says Nutro, Natures recipe is working well, do not use store brand. If you rather want to use raw meats she suggests Country pet dog food
www.countrypet .comLast fruits and veggies, says it has not to be a lot, a little is better than nothing, she lists some fruits and veggies you can use banana, apples (not the seeds), tomatoes, carrots, broccoli, cauliflower, oranges, sweet potatoe, squash, green beans, zuccini, garlic
Other things she adds to the "how to's" is that the kibbles is to be fed with water in it, not ever soaked as that destroys nutrients. But the water makes the dog not over consume water after the meal, and the kibble does not pull moisture from the dogs system in order to break down. Never real warm water though since that destroys the probiotics. Mix up and feed straight away, she uses 1,5 cups per adult serving
That is a lot of information I know, but this lady is one person I truly have trust in when it comes to feeding and how to deal with different issues due to feeding. It may be too much for you, but it is probably worth a try, she states that she has used this on IBD dogs with very good result.
