Background
Ephrin-a receptor 7, also known as EphA7, belongs to the Ephrin receptor subfamily of the protein tyrosine kinase family. The Eph family is the largest group of related receptor tyrosine kinases known, consisting of 16 members in the vertebrate genome. EPHA7 functions as a repulsive guidance molecule during the targeting of retinal axons to the superior colliculus and of neocortical axons to the thalamus. At the same time, in recent years, more and more studies have shown that EphA7 protein is abnormally expressed in a variety of malignant tumors, involved in tumor occurrence and metastasis, and correlated with patient prognosis.

Review of Outward Hound Durablez Snake – Squeaky Plush Dog Toy, No Stuffing for Less Mess, Interactive & Tough, 6 Jumbo Squeakers, Puppies & Dogs, X-Large, 40"
My best friend brought her 16-month-old German Shepherd up for a visit and I happen to love him to pieces! A few months ago, I bought the smaller version of this same toy snake for him and he LOVED it. Many squeaker toys he has eventually torn up, as puppies and others do. The smaller only has a small tear in the butt-end from playing some minor tug of war with it. This larger version is made just as well and with the same materials. It is very durable, but there are no toys indestructible. The only difference is the length, and it has 6 JUMBO squeakers as opposed to 5 smaller ones. It got here on the day of this post and he has not stopped playing with it! Now if you’re one that squeakers get on your nerves, this is not for you. But, if you’re like me and truly enjoy watching (and hearing) a fur baby having so much fun, then buy this now! The price is very reasonable in my humble opinion. It is Ryker Der Hauswolf approved and I recommend it.

Absolutely one of the best chew toys I've ever bought my dog
Size: Large (Pack of 1), Color: Green Gecko
Absolutely one of the best chew toys I've ever bought my dog. She's a lab-pit mix, about 70 lbs, loves to chew, and is almost pure muscle. There are no half-measures with my dog. When she plays tug of war, she's playing to win. Often, she ends up whipping her entire body back and forth violently to get that thing out of your hands. Playing with her feels like you're pulling against a freight truck. I've never had a plush chew toy last longer than 15-20 minutes. It rips, and suddenly out comes all the stuffing and squeakers. Impossible. I just stopped buying her plush toys altogether, which was such a shame because I know that's her favorite thing ever. But when I saw this on Amazon, I thought I'd give it a try. I wasn't expecting much, nothing is truly invincible. BUT THIS THING IS TOUGH! It's my dog's favorite, she loves the squeakers so much, and so we've played tug of war or keep away nearly every day since I bought it. Yeah, there's a small hole in it now, the fur's a little matted and it doesn't look at pretty as when I bought it, BUT IT STILL LIVES! It's lasted three whole months, which is miracle given my dog's seriously aggressive play style. Squeakers are intact, the black lining has held up, I really can't believe it. I've even given her free reign with it over the past couple of weeks, as I have another one saved for the day this finally dies. Even though she's allowed to take this thing behind the couch and really go at it in a serious chew session, she can't break that black lining. Amazing product.

Cute? Yes! Durable? Not so much…
Size: Large (Pack of 1), Color: Green Gecko, Size: Large (Pack of 1), Color: Green Gecko
Upon opening this toy I was hopeful that it would last my dog (medium size beagle mix) quite a while. While he enjoyed it, he was able to start ripping it up less than 24 hours after getting it. Now 10 days later, he’s completely destroyed it. He was able to rip open all layers of material, pull them apart, and tear all the squeakers out. While the squeakers are large, they could be a choking hazard for a large dog. Based on the advertised “durability” of this toy and how little time it lasted my dog, I would not purchase it again.

This worm, pretty sure it’s a worm and not a snake, can take a lot of abuse.
Size: X-Large (Pack of 1), Color: Blue Snake, Size: X-Large (Pack of 1), Color: Blue Snake
Snake, worm, whatever, my dog doesn’t care, she loves it all the same. My little friend can be kinda rough with her toys. This is no exception. The pictures are from roughly one month of giving it to her and include playing with it at least every other day or so. The top is holding up well, but the bottom has taken some damage, and two of the squeakers have long since been destroyed. Despite this, my dog still loves playing with it. We normally play tug of war together, but on her own she chews at it to get to the squeakers inside, which she promptly destroys, which I’m totally fine with, as quiet toys are much preferred, by me, not her. I believe there are 4 in the XL size that we got. We’ve had a few of these in the past. We tend to get about 6 months out of them. After she “lovingly” removes the squeakers, she doesn’t chew on it much, and we just use it for tug of war, but at that point she’s done enough damage to the underside that its time is limited. But, as it’s pretty low priced, for the time and enjoyment we do get out of it, it’s very much worth it. I do need to clarify, the durability is actually quite good, I don’t fault the product as at all, it’s just my dog is equally as good with destruction, but it should be noted this toy does last much longer than most of her victims. The color, (we got the blue and green) is also very vivid and nice, as is the texture. We’ll be purchasing again.
