Minnie Aussie can chew these down to a stub but takes lots of work and totally takes her stress away. Only kind I'm buying in different varieties. Yes I've tried them all for my aggressive chewer and these have been the best. I've gone through a lot of these but are lasting about week with supervision. Make sure your buddy has plenty of water and give them in 1/2 hr increments.

Good purchase, dog loved it, lasted months

Size: 8 Inch, Color: Tree Branch

My dog loved it, took several months before she destroyed it. I did eventually have to throw it out because she managed to start breaking pieces off and eating it.

Dog Loves It, But Durability/Safety Major Issue

Size: 8 Inch, Color: Tree Branch

My 9 month old Frenchie loves it, but she got pretty sick this weekend and was vomiting all day...next day she finally threw up a big chunk of this toy...just beware if your dog is a heavy chewer, this may not be the right fit for you. Not the best durability...

She loves them, therefore I love them too

Size: 5.5 Inch, Color: Ring Toy

My furbaby LOVES these, especially the peanut butter flavored ones. I still regularly brush her teefers, but these do help with dental care.
