Hi, I'm sorry about your baby having LP. I honestly don't know a lot about it so I'm sure others here can help you more. I do know that there are differen't grades of LP. I think it's grades 1 to 4 or possibly 5. The higher number being the worse. Since your baby is only a one that is a good thing. I would talk to your vet about a good suppliment. They can help to keep your baby's knees from getting any worse. Also, try not to let your baby jump on or off of anything. Puppy steps would be a great idea.

Some babies do have to have surgery because of the LP but typically it's when the grade is 3 and up. However, babies with a lower grade can require the surgery.
You asked about breeding and I'm not sure if you were planning to breed your pup but please don't. Please don't take me as being rude but LP is genetic and no good breeder would breed their babies knowing that they have this. In my opinion it is just very wrong to do. I hate it even more when the breeder claims that they didn't know the mom or dad had LP and yet the baby will have a terrible grade or they'll claim the parents don't have it.

How didn't they know about the mom or dad having it? It's just a big lie!!! Any good vet checks for this and would have told the breeder.
The suregery is expensive and tons can't even afford it. Not just being a money issue but the poor babies are the one's that have to suffer. Like I said before, not trying to sound rude but breeding a dog and knowing it has LP is so wrong to me. I wish you all the luck with your baby and I hope the grade remains at 1.
