The recommendations on chew items are so inconsistent! My vets pretty much say not to give anything that might cause a problem but what the heck is left once you eliminate everything that might be dangerous? I've given compressed rawhide bones but have also been told not to give them because the shards may be sharp- but the pieces they chew off are hopefully too small to cause problems. There's only one Nylabone item my younger dog likes to chew, although I have several choices here, and that was this nubbly lightbulb shaped thing that I cannot find anywhere to replace it.
I have used antlers- my older dog had no interest in them, ever. My younger dog liked them when she was little, now she doesn't seem interested in them. Here's where I got them- they are not inexpensive but cheaper than a new sofa or replacing the door frames! Grateful Shed Antler Chews for Dogs, Wholesale to the Public
I use large thick rawhide retriever rolls under supervision so they hopefully never swallow a huge hunk, so that usually means 15-20 minutes of chew time. My older dog mainly just chews on them, the younger one rips them apart once she gets an edge worked up enough. I buy the Wholesome Hide super thick retriever rolls, which are available from different sources but here's where I've gotten them: Wholesome Hide USA Rawhide Superthick Retriever Roll Dog Chew (10") | WhiteDogBone.com or Wholesome Hide Super Thick Retriever Roll- 10 Pack of Super Thick-Value Pack Super Thick
It's such a dilemma if you're a super careful pet owner. But then, my human kids would never have been allowed out of the house if I'd let my concerns for their safety overwhelm my ability to reason and supervise!
