Zara has been having problems with faecal fluid when the spring grass comes in until the autumn. Our vet said, 'There's a lot of fermentation going on in there. What do you expect?' I didn't expect to have to wash her bum and the inside of her back legs twice a day, tho' she didn't object. I ordered the taster pack to see if she would eat it. Success! No objections to the taste. Then I ordered the starter pack and the bum washing started to decrease after a few days. We are now have the next size pack on regular delivery and her bum is clean and her poos don't resemble cow-pats. I am very satisfied with the B-complete gut support. Great product and a lovely company to do business with.
