Golden approved
My golden retriever’s really enjoy these chew toys. They are pretty durable and last awhile. They are hard plastic but they do get rough edges after they’ve been chewed in for awhile

Mixed Results: SIHRMIU Dog Chew Toys Offered Stimulation, Limited Interest from Aggressive Chewers
I recently purchased the SIHRMIU 2 Pack Dog Chew Toys for Aggressive Chewers with hopes of providing my energetic dogs with both entertainment and stimulation. While these toys boasted durability and were designed to alleviate boredom, my experience with them yielded mixed results. Upon receiving the chew toys, I appreciated their sturdy construction and the promise of durability, which was essential given my dogs' penchant for aggressive chewing. The variety of textures and shapes seemed promising, offering potential for engaging play sessions that could keep my pets occupied and mentally stimulated. Initially, my dogs showed some interest in the toys, eagerly sniffing and exploring them. They seemed intrigued by the different textures and shapes, and I was hopeful that these toys would provide the entertainment they needed. However, as my dogs began to interact more with the toys, it became evident that their interest was short-lived. While they engaged with the toys for brief periods, they quickly lost interest and returned to their usual chewing favorites. Despite their designation for aggressive chewers, the toys did not seem to withstand the intense chewing of my pets as well as expected. Within a short time, I noticed signs of wear and tear, with pieces starting to break off. While the SIHRMIU dog chew toys offered some stimulation and diversion for my dogs, they ultimately failed to hold their interest or stand up to their aggressive chewing habits. While they may be suitable for dogs with less voracious chewing tendencies, they were not a perfect fit for my pets. In conclusion, while these chew toys have potential and may work well for some dogs, they fell short of expectations for my aggressive chewers. I appreciate the effort put into their design and durability, but unfortunately, they did not meet the needs of my furry companions.

Great for tough chewers!
Color: carrot orange
This is awesome for my 85# Labrador. He is very destructive with toys and this has held up great. After months of playing with it, only teeth marks on it. Worth every penny. The green top crinkles which my dog loves.
