Background

The 50 kD protein is a DNA binding subunit of the NF-kappa-B (NFKB) protein complex. NFKB is a transcription regulator that is activated by various intra- and extra-cellular stimuli such as cytokines, oxidant-free radicals, ultraviolet irradiation, and bacterial or viral products. Activated NFKB translocates into the nucleus and stimulates the expression of genes involved in a wide variety of biological functions. Inappropriate activation of NFKB has been associated with a number of inflammatory diseases while persistent inhibition of NFKB leads to inappropriate immune cell development or delayed cell growth. Two transcript variants encoding different isoforms have been found for this gene.

Harder and heavier than a dog toy should be, but it is sturdy.
Color: Mixed Blue
The outer rim is a very hard plastic, hard enough to dent and ding furniture. Too hard to throw in the house. Dog likes it but has difficulty getting his mouth around the sides as the item is very heavy for its size. Squeaker in the middle was a a nice surprise. Would not buy again.

Durable and well made.
Color: Mixed Blue
Our dog will chew any toy up in 2.5 seconds. This has lasted for quite some time. It's super hard which can be a downfall because they lose interest. Squeeker is hard to push down but overall it's outlasted other toys.

Dog toy
Color: Mixed Blue
Glad I bought this. My dog job is to destroy her toys or she thinks so. This is great for her chewing and catching while it will be sometime before she destroys this one

Perfect Teething Toy for Puppies!
Color: Pacifier, Size: Small
My puppy absolutely loves this Nylabone Puppy Pacifier Chew Toy! The bacon flavor immediately caught his attention, and it has quickly become his favorite toy. It’s the perfect size for small puppies and easy for little mouths to carry around and chew on. The material is soft enough for teething but still durable enough to hold up to daily chewing. It has really helped redirect my puppy from chewing on furniture and shoes, and it seems to soothe his gums while he’s teething. I also like that it keeps him entertained for long periods of time. Great quality, puppy-approved, and definitely worth buying for any small dog owner!
