Progressive Retinaatrophie, Cone-Rod Dystrophie 2 (PRA-crd2)Die meisten der bekannten Mutationen bei Hunderetinalerkrankungen sind Stbchen Zapfen Degenerationen, auch bekannt als progressive Retinaatrophien (PRAs), die durch progressive, von Stbchen gefhrte Photorezeptor Degenerationen gekennzeichnet sind, gefolgt vom Untergang der Zapfenphotorezeptoren. Im Gegensatz dazu sind Zapfen Stbchen Dystrophien durch den relativ frhen Verlust von Zapfenphotorezeptoren gekennzeichnet. Crd2 PRA betrifft normalerweise

Die meisten der bekannten Mutationen bei Hunderetinalerkrankungen sind Stäbchen-Zapfen-Degenerationen, auch bekannt als progressive Retinaatrophien (PRAs), die durch progressive, von Stäbchen geführte Photorezeptor-Degenerationen gekennzeichnet sind, gefolgt vom Untergang der Zapfenphotorezeptoren. Im Gegensatz dazu sind Zapfen-Stäbchen-Dystrophien durch den relativ frühen Verlust von Zapfenphotorezeptoren gekennzeichnet. Crd2-PRA betrifft normalerweise sehr junge Hunde (jünger als 1 Jahr) und verursacht schwere photopische und skotopische Sehbeeinträchtigungen, die im frühen Erwachsenenalter zur vollständigen Erblindung fortschreiten können. Die Mutation, die crd2-PRA verursacht, wurde bei American Pit Bull Terrier Hunden beobachtet. Da American Pit Bull Terrier und American Staffordshire Terrier eng verwandte Rassen sind und manchmal gekreuzt werden, ist es möglich, dass die gleiche Mutation auch beim American Staffordshire Terrier auftritt.

Vererbung: autosomal rezessiv

Mutation: IQCB1-Gen

Gentest: Die für den Test verwendete Methode ist äußerst genau und ermöglicht eine vollständige Unterscheidung zwischen betroffenen Tieren, Trägern und gesunden Hunden. Der Test kann in jedem Alter durchgeführt werden.

Great quality
Color: Four colors, Size: 5cm (ball only)
I was very surprised that these are as good as the chuck it balls. I have a super chewer and he’s tears balls up except for chuck its and he can’t tear these up.

Awesome price for quality balls
Color: Four colors, Size: 5cm (ball only)
These balls are super bouncy and durable. My dog loves them and for the price these are totally worth it! I think they are as durable as nerf balls and equal in size, and much cheaper!

Rope comes out at the slightest force. Pointless tug toy!
Color: Four colors, Size: 6cm (with rope)
If your dog pulls on these (and why wouldn’t he?), the rope immediately comes out. Turns out they just fuse the ends of the nylon rope together, which is no match for a dog playing tug. Any dog, any level of pulling will dismantle these. We’ve managed to reinsert the rope to a couple of these and KNOT it, which gives you a shorter rope but a toy that can withstand some play. But if I had wanted a DIY toy, I’d have used the balls and rope I already own.

Not for super chewers!
Color: Four colors, Size: 5cm (with rope), Color: Four colors, Size: 5cm (with rope)
These rope ball toys arrived today. My poodle puppy loves rope ball toys and playing tug of war. These didn’t last 10 minutes. For context, she is 1 y.o., 30 lbs., is not teething & has her adult teeth. She did this on her own- we were not playing tug of war at the time the toy fell apart. At least there are 3 more in the package & when the rope is done, we’ll still have the balls to play with.
