SpikeyBush, //Some say you shouldn't give dogs raw bones as it can lead to constipation. I say that is complete rubbish.//
no its not "rubbish" we feed our hounds bones and if fed in moderation there isnt a problem but if you feed too many they can suffer from severe constipation. When the comes out can be white and very hard and dry, it can be so dry that when it hits floor it can be powdery and will fall apart.
When we feed bones we usually try to five them some raw liver to help the bones through, it works a treat.
