Background

Human Epidermal growth factor Receptor 2 (HER2) is also called ERBB2, HER-2, NEU, NGL, TKR1 and c-erb B2, and is a protein giving higher aggressiveness in breast cancers. It is a member of the ErbB protein family, more commonly known as the epidermal growth factor receptor family. HER2 protein cannot bind growth factors due to the lacking of ligand binding domain of its own and autoinhibited constitutively. However, HER2 forms a heterodimer with other ligand-bound EGF receptor family members, therefore stabilizes ligand binding and enhances kinase-mediated activation of downstream molecules. HER2 plays a key role in development, cell proliferation and differentiation. HER2 gene has been reported to associate with malignancy and a poor prognosis in numerous carcinomas, including breast, prostate, ovarian, lung cancers and so on.

Guidelines

Please conduct the experiments strictly according to the recommended dosage. If the grouping is not clear, the recommended dosage can be increased by 2 to 5 times.

Great toy for big chewers!
Have only had 3 days but my boy has been trying to destroy it and it’s holding up really well! Normally his toys would have been destroyed in 24 hours or less, including Kong and other brands advertised as tough!

Durability is no joke!
Excellent product! Our GSD puppy chewed it for the past 10 months and she is a pretty strong chewer. Only now did she manage to get a couple small pieces off of it, and WoofBite was quick to provide our one-time replacement. Great customer service! Will purchase more of their products and highly recommend!

So far so good
Had this for almost a month and no chunks have been chewed off yet. I have a lab who prefers chewing over pulling or retrieving type toys. She's destroyed everything we've given her --sometimes within minutes. She loves Wubbas but she chews them to bits immediately. Other toys get chunks or small pieces chewed off and we wind up throwing them away. This has lasted well. Full disclosure, we only pull out toys at the end of the day for just a couple of hours, and we are within sight of her the whole time, that's why 4 stars. But so far to our surprise this has held up very well.

Indestructible m
It’s actually indestructible. I have a black mouth cur who once ripped apart a Kong toy in minutes. Got him this and another ball shaped one for Xmas and 5 months later, there are just some puncture holes, no rips or chunks taken out! They’re in his top 3 favorite toys for sure!

Truly great quality for tough chewers
I seldom leave reviews, but after years of reading endless reviews for different dpg toy products that claim to be "indestructible" but end up being no match for our sweet but genuinely TOUGH chewer pitbull, I never expect much... so was so pleasantly surprised, no, shocked, by the quality of this WoofBite toy. Please note these photos are after about 3 months of use (and you may notice our dog is laying in a sea of other decimated toys that lasted only days, if not hours). Again, not a big reviewer, and I know no two dogs are the same, but if our experience is any indication, we felt we needed to make this recommendation to other bully breed owners out there who, like us, are skeptical of anything out there claiming to be indestructible. While our dog gets so much joy and takes great pride in the art of destruction, the endless revolving door of buying her new toys translates to lots of money spent. It is nice to finally find a new option to add to our very limited list of brands we will buy for her. Good news is, she still really enjoys playing with this toy and she is enjoying the challenge. I can confidently say this has been a GREAT buy for our spoiled little pitbull and we will be scooping up more for her grandparents house, our summer camp, and some backups just in case these ever become unavailable. Thank you!
