Bare with me...this is weird.
Brown, my chocolate lab, is allergic to corn. Apparently this occurred as he got older. He didn't have this problem in his younger days. His diet, however, isn't the problem (I feed Solid Gold)...it's our cat litter! We use World's Best, which is corn, and even though it doesn't track very much, Brown will find some to lick up, which eventually causes an ear infection. I told his vet about this, and he had to laugh because it's not often a dog has an allergic reaction because of kitty litter. lol
Anyone have another litter suggestion. I love World's Best. We have 3 cats, and the litter doesn't smell or track, and I much prefer it to clay litters. Feline Pine and Yesterday's News didn't work well for us. Any ideas?
