I used to post on this forum when my lab was a pup... he's 3 now!
Rico has HMLR, and it was just being diagnosed when I was posting here. He is doing great though. My vet told me she has put down a few other labs due to this disease since I first brought Rico in, but he has never developed any of the severe symptoms, he just looks like a dog that doesn't have a lot of muscles (cuz he doesn't lol). He is still very much a retriever though - he can chase a ball for hours. I have also raised a few huskies... they have generally come to me from other people, and I've raised them and eventually found new homes for them, but I am very familiar with the breed. That's about it!
