Are these as bad for dogs as the rawhide chews? Still trying to find something my dog really loves to chew. He loves rawhides but I don't want to give him them any more as he gets through them (totally consumes them) very quickly and I know it's not great for their digestion. I can't find any local butchers who'll give me 'real' bones. Got some 'stag bars' as recommended on here and they seem great but don't hold his interest for long. He seems to empty out kongs very quickly, even if frozen. What else can I try? Thanks.
