Der D-Lokus ist verantwortlich für die Verdünnung der Fellfarbe. Bekannte Mutationen des MLPH-Gens (Melanophilin) sind verantwortlich für die meisten Fälle von verdünnten Farben. Das MLPH-Gen kodiert für ein Protein Melanophilin, einen Schlüsselbestandteil in der Bildung von Haar- und Hautpigmenten. Eine Mutation im Gen verursacht die unsachgemäße Verteilung von Melanosomen und die Verdünnung der Fellfarbe. Es hat einen Einfluss auf die Bildung von schwarzem Eumelanin sowie rotem-gelbem Pheomelanin, jedoch in geringerem Maße. Die Verdünnung des schwarzen Pigments führt zu blauer oder grauer Fellfarbe, und die Verdünnung des braunen Pigments führt zu hellbraun oder Isabella. Der D-Lokus ist nicht nur für die Verdünnung des Fellpigments verantwortlich, sondern verdünnt auch das Pigment von Nase, Pfoten und Augen.

In unserem Labor testen wir 3 verschiedene Allele im MLPH-Gen, die für die Verdünnung der Fellfarbe verantwortlich sind:

  • Allele d1: ist verantwortlich für die Verdünnung der Fellfarbe bei vielen Hunderassen

  • Allele d2: ist vorhanden bei Chow-Chow, Sloughi, Thai Ridgeback und Französischer Bulldogge

  • Allele d3: ist vorhanden bei Chihuahua, Mudi, Pumi, Italienischem Greyhound, Pekinese, Shetland Sheepdog, Shih Tzu, Tibetmastiff und Yorkshire Terrier.

Bei einigen Hunderassen können mehrere verschiedene Mutationen gleichzeitig auftreten. Die Kombination von zwei Mutationen (d1/d2 oder d1/d3) führt ebenfalls zu einer verdünnten Farbe des Fells.

Great dog chew lasts a while, enjoyed by most every dog
These bones are great for a few small, yet significant reasons. Bottom line up front: They're great and a dog owner would be well served to pick up one or two of these as a long term chew toy your dog is almost sure to love. 1) The first being the odd shape of the bones. The shape enables the dog to pick up the bones with ease rather than some of the more flat bones or chews which can lead to a struggle and frustration. The three prongs and the elevated middle portion alleviate this concern. 2) These bones aren't ground material shaped into a bone shape, they are tough, plastic-like substances. They have a very subtle aroma of the flavor they are supposed to be (bacon, chicken, etc) but are completely safe for the dogs to munch on. The best part of the bones being this substance is that they last quite a long time. 3) The bones are lightweight and won't hurt you if you stub your toe as you walk around the house barefoot. 4) Dogs seem to love them. Only the most picky or reclusive dogs will ignore these bones.

Good size, lasts a long time
Dog likes these. She has her moments when this is only chew toy she wants, and spends days gnawing on it. She likes these bacon and chicken flavors. I like the fact that there is no squeak. This is a good size for full size Aussie, and I also like that she doesn’t “throw” these at me, she lays on the couch or floor and chews. They help to keep her teeth clean from plaque and tartar, so to me they are very functional. This is 4th or 5th buy again, so I wouldn’t buy again if she didn’t like. It does take a while for her to chew to point of needing new, since I keep variety of chew toys for her.

Awesome!
**update: we have had this toy for over a year! I have found one other con. Once chewed if you step on it you will immediately drop to the floor in agonizing all encompassing pain or (my personal favorite) say every dirty curse word you have ever heard while clutching your destroyed instep. BUT even though this chewed bone is the demon child of a LEGO and a race car to step on my dogs still love it, still chew it and we haven’t had to replace it yet! I have an insane chewer where toys usually last us less than 24 hours. It has become almost impossible for us to keep up with toys because of how expensive it has become. This toy is not only insanely durable but she has not left it alone for the 3 days we’ve had it. I was concerned that being “chicken flavored” would mean stinky or sticky and I was very pleasantly surprised that it was neither! It doesn’t leave a stain once chewed, it doesn’t smell, and it doesn’t have a weird coating on it. The only con so far is that due to it being so durable and hard it makes a loud noise when dropped on the tile or hardwood which made her nervous toward it at first but now that she’s started working on it she could care less about the noise. Super happy with this purchase and will 100% buy more in various sizes for our other pups.

⭐⭐⭐⭐⭐ FINALLY! A toy that can handle my furry demolition expert!
Flavor Name: Beef, Size: Large
Let me tell you about Moxie, my 97-pound Rottweiler who has made it her life's mission to destroy every single toy that dares enter our home. This girl has teeth that could probably open cans and jaws that make nutcrackers jealous. I've spent more money on "indestructible" dog toys than I care to admit, only to find sad little pieces scattered across my living room within hours. BUT THEN... enter the Tikaton Indestructible Dog Chew Toy! 🎉 I'll be honest - I bought this with zero expectations. Just another victim for Moxie's reign of terror, right? WRONG! This bone has been in our house for THREE MONTHS and it's still going strong! Sure, Moxie has made some progress (she's persistent, I'll give her that), but this thing is holding up like a champ against her industrial-strength chompers. The best part? Moxie is absolutely OBSESSED. She carries this bone around like it's her precious treasure, gnawing away contentedly for hours. It's given my furniture, shoes, and sanity a much-needed break! Pros: Actually lives up to the "indestructible" claim (mostly!) Keeps my destruction-loving pup busy for hours Great value - lasting months instead of minutes No weird smell or toxic materials Cons: Nothing is truly indestructible when facing Hurricane Moxie, but this comes pretty darn close! Fellow owners of canine wrecking balls - THIS IS THE ONE! Your wallet and your home will thank you. Update: Month 4 and still chewing! Moxie approves this message with enthusiastic tail wags.
