No good for anal gland problems!
My labradane has no end of trouble with anal glands. Bought this as it states that it firms stools and good for anal gland problems. All it did was give him VERY soft stools and made problem worse. I also tried it out on my staff/mastiff cross with the same result. Eventually I gave the food to my mum for her retriever, who also ended up with soft loose stools.
The only plus side is that my constipated patterdale terrier can now poop a little more comfortably, as her stools are softer on it!
