Description

B-Lokus (Australian Shepherd)Das Gen TYRP1 (Tyrosinase verwandtes Protein 1) ist verantwortlich fr die schokoladen leberbraune Farbe bei Hunden. Diese Fellfarbe wird rezessiv vererbt. Es gibt 4 verschiedene Varianten am B Lokus bei Australian Shepherds: bc, bs, bd und baus. Eine Kombination von zwei rezessiven Allelen fhrt zu schokoladen leberbrauner Farbe (zum Beispiel zwei bc Allele oder ein bc und ein bs Allel). Da das TYRP1 Gen mit der Eumelaninproduktion verbunden ist,

Das Gen TYRP1 (Tyrosinase verwandtes Protein 1) ist verantwortlich für die schokoladen-/leberbraune Farbe bei Hunden. Diese Fellfarbe wird rezessiv vererbt. Es gibt 4 verschiedene Varianten am B-Lokus bei Australian Shepherds: bc, bs, bd und baus. Eine Kombination von zwei rezessiven Allelen führt zu schokoladen-/leberbrauner Farbe (zum Beispiel zwei bc-Allele oder ein bc- und ein bs-Allel).

Da das TYRP1-Gen mit der Eumelaninproduktion verbunden ist, betrifft es nur Hunde, die den Genotyp E/E oder E/e am E-Lokus haben. Der B-Lokus beeinflusst auch die Farbe von Nase, Augen und Pfoten. Hunde mit dem Genotyp e/e produzieren nur Pheomelanin im Fell, aber die Produktion von Eumelanin in der Nase, den Augen und den Pfoten ist nicht betroffen und wird daher vollständig vom B-Lokus kontrolliert. Je nach Genotypen der E- und B-Loci kann ein Hund ein gelbes Fell und eine braune Nase/Augen (e/e, b/b) oder ein schokoladenfarbenes Fell und eine braune Nase/Augen (E/e oder E/E und b/b) haben.

Der Test für den B-Lokus bei Australian Shepherds besteht aus vier separaten Tests, um das Vorhandensein von rezessiven Allelen (bc, bs, bd und baus) zu finden. Die Ergebnisse werden sowohl als kombinierte Ergebnisse als auch als Ergebnisse für jedes getestete Allel berichtet.

Genotyp

Beschreibung

B/B:

Der Hund ist homozygot für das normale Allel; es sind keine rezessiven Allele für schokoladen-/leberbraun vorhanden, der Hund wird dominante Allele an die gesamte Nachkommenschaft weitergeben.

B/b:

Der Hund ist heterozygot für schokoladen-/leberbraun, wenn eines der rezessiven Allele vorhanden ist (zum Beispiel Bc/bc, Bs/Bs, Bd/Bd), die braune Farbe wird nicht ausgedrückt, ein rezessives Allel kann an die Nachkommen weitergegeben werden.

b/b:

Der Hund ist schokoladen-/leberbraun (homozygot für die braune Farbe) in eumelanin-pigmentierten Bereichen und trägt mindestens zwei rezessive Allele (identisch oder unterschiedlich), was bedeutet, dass der Hund entweder homozygot für ein Allel ist (zum Beispiel bc/bc, Bs/Bs, Bd/Bd) oder heterozygot für zwei Allele (zum Beispiel Bc/bc, Bs/bs, Bd/Bd).

Wenn zwei, drei oder vier Einzelkopie-Varianten von bc, bd, bs oder baus nachgewiesen werden, kann das Vorhandensein mehrerer Varianten auf einer Einzelkopie des Gens nicht ausgeschlossen werden. Daher könnte der gesamte B-Lokus-Genotyp für einen Hund B/b oder b/b sein (der Hund kann schwarz oder braun erscheinen) und kann vom Labor ohne zusätzliche Tests der Eltern nicht bestimmt werden.

Adorable Toy Set for Small Dogs, But Supervision Is Important
Color: Pink, Color: Pink
The first thing that caught my attention was the beautiful pink color. For a small female dog like mine, this set looks absolutely adorable. The toys are cute, colorful, and perfect for small breeds. When I opened the package, I honestly thought they looked even prettier in person than in the photos. My little dog was immediately interested in them and couldn’t wait to start playing. The variety of shapes keeps things fun, and the rubber pieces seem great for chewing and keeping small dogs entertained. My only concern is with the fabric ribbons attached to some of the toys. My dog loves to chew on everything and has a talent for pulling things apart, so I personally plan to remove the ribbons before giving the toys to her. I worry that an aggressive chewer could tear off a piece and accidentally swallow it. For supervised play they’re fine, but it’s something I would keep an eye on. Pros: * Beautiful pink color * Adorable design for small dogs * Variety of toys included * Great for chewing and playtime * Looks exactly like the photos Cons: * Fabric ribbons may not be ideal for dogs that aggressively chew or destroy toys * Requires supervision for heavy chewers Overall, this is a very cute toy set that my dog immediately loved. The colors and designs are adorable, and the toys are perfect for keeping small dogs busy. Just be mindful of the fabric ribbons if your pup is the type who likes to tear everything apart. Other than that, it’s a lovely set and a great gift for a small dog.

All Five Toys Are Mine Now — A Review by Patches the Pomeranian
Color: Pink, Color: Pink
⭐ “Hi, I’m Patches, and These Toys Are All Mine Now” — A Review by a Very Busy Pomeranian ⭐ Hello, my name is Patches, and I am what the humans call a “toy enthusiast.” What that really means is: if a toy enters this house, it belongs to me immediately, no questions asked. The Pack Leader brought home this 5‑Pack Puppy Chew Toy Set — a pea pod, a wing‑shaped chew, and three cute fabric‑tied toys. Five toys. Five opportunities for greatness. Five items for my personal collection. He tried to hand one toy to each of us like we’re participating in some kind of polite sharing ceremony. Very sweet. Very unrealistic. The moment my sisters glanced away for a single second, I activated my elite move: The Pomeranian Slide‑In‑and‑Snatch. I took my toy. I took their toys. I took the toys on the floor. I would’ve taken the mail if it looked interesting. Now I have all five toys, and my sisters have… well… the joy of watching me parade around with them like a tiny fluffy champion. 🦴 My Professional Toy Review Pea pod: Chews beautifully and looks adorable when I carry it around like a prize. Wing bone: Excellent for dramatic chewing sessions. Fabric toys: Perfect for shaking, tossing, and showing off. They don’t squeak, they don’t bounce — and honestly, that’s perfect. I enjoy a quiet chew while plotting my next toy acquisition. 😬 Teething & Dental Stuff The humans say these toys help clean teeth and massage gums. I don’t know about all that. I just know they feel good to chew and keep me busy while my sisters stare at me in disbelief. 🎁 Final Thoughts If your puppy enjoys chewing, collecting, or claiming ownership of everything within paw‑reach, this set is a fantastic choice. 5/5 stars. Would absolutely claim again.

Anya loves her new baby toys
Color: Pink, Color: Pink
This review is for the YZHZIIR 5 Pack Puppy Chew Soft Rubber Dog Toys. As you can see in my photos, my Borzoi “puppy” is quite large. I knew these toys are not meant for extra large breed puppies, but for some odd reason, ours loves little tiny toys. She usually will just carry them around in her mouth and will gently play with them. That being said, she will have these baby toys in her “supervised only” drawer. This order came with 5 toys per pack, as stated on line. They look exactly like what you see, and it even specifies the sizes. I think if you have a toy breed, these are suitable since they’re safe to chew (not ingest). They’re BPA and phthalates free, made of natural rubber, so I’m not concerned about her developing a third eye or a lump somewhere on her body. My puppies are the apple of my eye, so they are supervised whilst playing with small, easy to tear apart toys or goodies that may have a choking hazard. So my recommendation is that unless you are keeping a close eye on them, stick to giving these to toy breeds with tiny teeth, or very young puppies who could barely chomp down on soft puppy food. The price is unbeatable. For 5 toys, you pay only $9.99!

Made Puppy Sick!
Color: Blue, Color: Blue
Fell apart fast, my pup tore pieces off and it made him sick. I really wanted these to work because they are so cute as "baby" toys for puppies and the listing promises “durable & chew‑resistant” toys that can stand up to sharp puppy teeth and even says they’re safe for extended chewing with no health risks because they’re made from “100% natural rubber” with no BPA or harmful chemicals. Unfortunately, that wasn’t my experience at all. My pup had these for only a short time before he chewed pieces off, and the toys started breaking apart way faster than expected. After swallowing some of the pieces, he ended up sick to his stomach, which meant the toys had to go straight in the trash. He was up all night with diarrhea and vomiting, at first, I didn't put it together until I found blue pieces of the rubber toy in his vomit.

good toys but better for gentle / non aggressive teethers
Color: Blue
cute but not very durable. better for dogs who are not aggressive chewers even though they are young pups. when they are broken apart by teeth, the pieces are at least clean cuts. no big concerns of ingestion
