We have 4 von der Otto dogs. One is from the 2014 Karson x Xena litter and is an awesome dog. Very healthy, beautiful color, and great temperament. Our second dog was from the 2018 Nix x Sadie litter and had a heart murmur when we brought her to our vet about a week after she came home. We took her to a cardiologist who diagnosed her with mitral valve dysplasia with left ventricular outflow tract obstruction, a congenital condition. Initial prognosis was a lifespan of 6 months, but she has responded better than expected to the medication and vets are now saying she should make it several years. Per the breeder's contract we did get a full refund on this puppy. Our next von der Otto dog was from the 2018 Aaron x Lessy litter. She's a long coat and very sweet, but very stubborn dog. Doesn't have the "willing to please" attitude of our past shepherds, though she is very cuddly. She also has soft (floppy) ears. While being boarded at the breeder recommended trainer's facility, the trainer had the breeder "tape" the ears with cardboard forms. The forms got wet and the ears fell, but we were told we could not take the forms out, we had to wait for them to fall out on their own and then redo them. So when we got the dog back from the trainer she had floppy ears with cardboard forms. We took her to an ear specialist who tried a couple different styles of taping, but ultimately said she did not have enough cartilage for her ears to ever go up. She couldn't say if the lack of cartilage was genetic or from trauma. Our fourth von der Otto dog is Sadie, the retired mother of the puppy with the heart condition. She is also very sweet, but we recently had x-rays done and she has moderate hip dysplasia in one hip. She is a trooper though, and still plays with the other 2 younger dogs. I'm just sharing what we've experienced with our von der Otto dogs and what our vets have told us. I am not in any way trying to breeder bash.
