My Springer Spaniel puppy loves the camel hide chews and can spend half an hour gnawing away. One chew lasts ages and they keep fresh when re-sealed in the bag. Perfect for giving us a little peace in the evening! His teeth are sparkling white - he is only 6 months, but I am sure that this healthy chew is good for his teeth and gums. He also loves the beef jerky and the white fish sticks, but they do not last as long!
