Background

PSA (prostate-specific antigen) is a single-chain protein containing 237 amino acids, belonging to the tissue-specific chymotrypsin-like serine protease family, which can break down the main mucin in semen and liquefy semen. PSA is tissue specific and only exists in the cytoplasm of human prostate acinar and ductal epithelial cells. PSA is not tumor-specific. Prostatitis, benign prostatic hyperplasia, and prostate cancer all lead to an increase in total PSA levels (free PSA plus combined PSA).The main function of PSA is to decompose the colloidal protein in semen, liquefy the colloidal semen and enhance sperm mobility. Small amounts of PSA can leak into the blood from the prostate. However, the increase of PSA in serum is seen in pathological states of the prostate, such as prostatitis, benign prostatic hyperplasia and prostate cancer. This product is the recombinant human PSA protein expressed from human 293 cells (HEK293).

Nice Value
Color: Consuela the Cactus - Large, Size: Large Dog
Very cute! Its soft and feels like it is well made. It is a heavier toy and a tougher one. Not a plush toy. I will order again for our older dogs. Nice value for sure!

Great toy for our best boys!
Color: Consuela the Cactus - Large, Size: Large Dog
You can never go wrong with BarkBox toys and this was no exception. Our dogs like toys that have squeakers and that they can tear into. This style of toy fits the bill. The design is cute as well. I’ve had this in the house for months and, while it’s definitely seen better days, it’s still intact and they haven’t gotten to the inner layer. (Not for want of trying.) The perfect type of toy for our fur babies.

Survives 7 months so far.
Color: Christmas Consuela, Size: Large Dog
It is still intact after nearly 7 months of constant play. My blue heeler normally destroys toys in just a few weeks. Consuela has exceeded expectations of survival with an extremely chewy, destruction prone dog.

Short-lived but much enjoyed as a chew toy
Color: Consuela the Cactus - Large, Size: Large Dog
I bought two of these for my "granddogs" in the size for Large dogs. The German Shepherd-mix stole the one intended for the border collie-mix and had both toys halfway destroyed within a day--I'm pretty sure they didn't survive much longer after that. Much enjoyed! Maybe I should've bought the Extra Large size, because the Large barely fit in her mouth and she wanted to play tug-of-war, so there wasn't much for me to grab onto. Then the border collie wanted in on the action (she's older, so she needed help tugging!) but there wasn't enough material for her to grab onto without accidentally sinking her teeth into me instead.
