I have a 11 month old Shar Pei that is a very enthusiastic chewers. I got him this chew toy based on the positive reviews. I gave it to him and about 2 hours later, he started vomiting up pieces of it. I found the toy and he had managed to gnaw off the end knobs completely. This might be a good toy for a less aggressive chewers, but not for my dog.

Not worth it

Doesn't last and pieces of the bone are all over. It makes a huge mess. My 15 lb Chihuahua mix has almost destroyed hers in 3 days.

My dogs love them and they aren't tearing the toys apart like normal

Size: Medium Chew Stick, Style: Pork Sausage

My dogs love these toys. So far they've actually lasted like they claim longer than the other toys that I have purchased. Like I bought a rabbit toy the same time as these two toys and ropes and the rabbit is completely destroyed and these toys are going strong. Pretty freaking cool Recommend 10 out of 10 worth the price.

Very strong smell!

Size: Medium Chew Stick, Style: Peanut Butter

Comes with extremely strong rubber smell and I am assuming taste. My dog would hardly even sniff it let alone chew on it. I even soaked it in water and baking soda for an hour and still very strong. Disappointed would not recommend. I will not be getting a scented chew again.
