I am looking for Flexible dog chew sticks, not the stiff ones. I had been feeding my adult male German Spitz All4Pets meat/chicken flavored dog sticks. On biting the sticks used to split into pointed edges which when swallowed whole used to cause colon/rectal bleed. Our vet has advised to look for flexible dog chew sticks that would not split into ridged pointed edges. What I see at dog spot are all inflexible hard chew sticks.
