Our Miniature schnauzer now 15 weeks old loves this. So far she’s been on the first 1 nearly 2 weeks and hardly made a dent, something which would be nice to know from other reviews and is often missed is the breed and age of dog because obviously some dogs chew through anything very quickly and from a young age…with our Lotti she manages to shave off tiny pieces and enjoys the challenge – would recommend over antler for pup miniature schnauzer 😁
