The Quest 506, available in 208/230V and 277V configurations, is the newest generation of the Quest “6-series,” surpassing the Quest 335 as the world’s most energy-efficient dehumidifier.

Durable
Style: Black chew toys for dogs
My hound dog seems to like hers. She greets me at the door every day with it in her mouth and she hasn’t been able to tear it up or get any little pieces in her mouth when she nib nibs on the edges. It doesn’t have a smell. It is hard. It seems safe I guess since they can’t pick it up with their paws and pop each other over the head with it but if you have an intruder it would be great to have in hand.

Surprisingly Tough Without Being Too Hard
Style: Black chew toys for dogs
The hardness on this bone is right in the sweet spot for aggressive chewers. It’s firm and durable enough that my dog hasn’t been able to tear chunks off or destroy it quickly, but it’s not rock-hard to the point where I’d worry about teeth damage. My dog usually goes through most toys pretty fast, and this one has held up really well. After extended chewing sessions, it only shows minor wear instead of deep cracks or breakage. It keeps his attention without splintering or becoming unsafe. If you’re looking for a bone that can handle strong jaws while still being safe for aggressive chewers, this one strikes a good balance and has been a solid option so far.

Not completly indestructible but good buy
Style: Black chew toys for dogs, Style: Black chew toys for dogs
Dogs loved this. I have 5 pot mixed and they all have enjoyed this. I ordered two more after they enjoyed the first one so much. So far my dogs have not been as destructive as they have been in the past (especially on my couches). I have been home more recently so it could be a combination, but I think the bones have been helpful. Sturdier than the red Kong toys, but not as indestructible as the black kongs. As durable or more than the ruff dawg balls, and much more affordable than all of those. Also, some of my dogs are more selective on toys, but this one was an immediate hit, even with my dog that has shown now interest in ANY chew toy. We even walked through pet smart one day, and i tried to get him to play with every toy on the shelf- and he was not impressed. I even showed him the scented toys that cost $40-50 each. Happy that he took to this immediately. Keep an eye out. I heard one of my dogs hacking and coughing from the other room, but by the time I heard it and got to the room, it wasn’t clear what he was choking on. I had three of these bones in the room at the time, but there was also food and such around so hard to tell. Recommend supervising your dog with the toy in the beginning at least.

Lasts with a pitbull
Style: Black chew toys for dogs
Good for very aggressive chewers. Even large, strong jawed dogs. My 70lb pitbull loves them and they usually last 6 months before we have to replace (because she's chewed slowly down the ends) Would recomment!
