DIEGO LOVES THIS CHEW TOY
Flavor Name: Peanut Butter, Size: Large
NYLABONE DURA CHEW BARBELL - PEANUT BUTTER FLAVOR Diego is soon to be two years old and loves to play with his toys and chew on NYLABONEs. NYLABONE is the ONLY bone we will let him have. NYLABONE brand is long lasting. This BARBELL bone has plenty of little nubs for him to clean his teeth on. He loves to carry it around and play with it also. This particular NYLABONE is made for the extreme chewer and that would be little Diego. NYLABONE products are veterinarian recommended. They are made in the USA. They are high quality. These NYLABONE products keep him happy, entertain him, and help keep his teeth clean. There no toxins involved the manufacture of NYLABONE products. Dogs naturally want to chew, so let yours chew -- on NYLABONE.

Excellent
Flavor Name: Peanut Butter, Size: Medium
I will purchase this again and again as long as it is made in the USA. I have bought this specific toy 3 times for one of my dogs. He still has all three of them. They are durable, long lasting and are not dangerous like some toys are if they start to come apart or after they’ve been chewed on for a while. With these chew toys, you can tell they’ve been chewed on but they don’t fall apart or come apart in large chunks. I watch my dogs with their toys and have had to take away other toys, even from Nylabone, because large pieces will come off or they will get too sharp where they’ve been chewed. Not this one. I’ll keep buying this one as long as it is USA-made. My dog has not damaged his teeth on this toy. I do get the wolf size which is good for dogs up to 50 pounds and he is 66 pounds.

Some dogs will probably love this.
Flavor Name: Peanut Butter, Size: Medium
My dogs were not very excited about this bone. I don’t think they are particularly picky, so I’m not sure why.

Depending on dog size, you may want to adjust bone size
Flavor Name: Peanut Butter, Size: Medium
This bone is attractive to both my 60 lb dogs. They're more light to moderate chewers at best but I remember when my youngest was a puppy, these things would buy me quite a few hours of quiet time. We repeatedly bought the ring style- must have had at least 5 as she was a rather voracious chewer. However, I don't mind replacing Nylabones one bit; they hold up well/can take A LOT of wear and make an excellent redirect for your bored puppy who ruined your favorite pair of shoes. I went down a size and bought a medium; I find that both dogs (full sized male Australian Shepherd + female lab/doberman mix) have trouble carrying a large size due to weight and this one is perfect for them! I would previously buy large ones who would barely ever get touched. However, you also don't want to buy one that's too small, so it's a fine line when you've got a dog who is somewhat in a weight range borderline.
