I booked this pup when he was born and was meant to picked him up next week but at his vet check it was found he has luxating patella in one of his back legs( he is a toy poodle).The vet said it kept popping in and out of the socket and graded it a possible 2-3 ut he hasnt seen a specialist yet.The breeder has offered to give him to me for no cost and also to pay towards any treatment he may need simply because she knows the bond we have built the last few weeks.Im getting mixed reports on what his future might hold so am keen to hear from anyone else who has had a puppy diagnosed at such a young age.The next step would be a specialist and that he most likely will need surgery but thats all i know.Thanks in advance

I've had 2 Toy Poodles needing surgery for patella luxation.  One was years ago, and the other more recently.  I use a grade 3 veterinary hospital and there are vets with all areas of expertise.  My first dog had both back legs done 6 weeks apart, I felt so sorry for her. 

My second, more recent experience was an eye opener.  The first had legs totally immobilised with RJ splints.  The second had no covering at all, looked horrible, like the chicken portions that you pick up at the supermarket.  But the outcome is down to the dog owner being resolute.  However good your surgeon it's up to you not to ruin his work.

Patella luxation is common in a lot of toy breeds.

You will not do your dog any favours by letting him run round the garden after surgery.  He will need crating for 12 weeks.  And going out for a wee will need you taking him on a lead.  The only folk I know who say that the surgery doesn't work just didn't have the staying power and "felt sorry" for the dog and stopped restricting movement.  I can only say that, by restricting movement for 12 weeks with my last dog, meant that she could do a standing jump to my shoulder once everything had healed.

There is no rush for this operation, and I'm sure that your vet will want to wait until pupster is older.  Just don't be tempted to rush things, otherwise it's a huge waste of £700.

personally I wouldn't have the puppy. knowing it has a health fault would be enough for me to say no even though it can be fixed. 
I would wait and find a puppy elsewhere or from this breeders next litter. you won't have any real bond with the puppy as yet because it's not living with you.  nice as it is that the breeder is offering you the puppy for nothing and also offering to pay for all its care in relation to the condition but I still personally would want a pup with no health issues and no need for any known operation.
Surely you want to take on a pup which is healthy from the start and keep knowing from the off it doesn't need to have an operation and weeks full of recuperation.
Yes things may crop up in dogs who do need to be operated on but I'd want one from the off who is healthy at the start of picking it up.
If you do have the pup make sure it's in the contract what the breeder is willing to pay re the condition.

I would have a really good think about this, taking on a puppy with known health issues is such a big commitment and you will find in hard to get insurance too, years ago I had a dwarf GSD puppy which was super cute and a friend fell in love with her and begged to have her. I gave her to the friend with a contract which stated that she would probably not live a long life and almost certainly cost a fortune along the way, she is still alive and has indeed cost a fortune although she did get insurance as her vet disagreed with the dwarfism diagnosis.  If you do go ahead then have a contract as to how much the breeder is actually going to cover, I don't like to be cynical but what will the breeder do if you don't have the puppy.

Interestingly when I read this yesterday, I immediately thought I'd NOT buy this puppy.  Sorry, but if the patella is bad, what else might you discover isn't right!!?   

And for sure I'd not rush into surgery either.   One of my girls went down some wooden steps when quite young, quite fast and ended up limping.  Now her rear wasn't quite as good as it should have been (not enough angulation) but when the vet we were using at the time checked her, he said her patella wasn't sitting in the grove 'as well as it might'.  And thought surgery necessary.   She was booked in, and rested meantime, and when I took her in, later on I had a phonecall to say he wasn't going to operate after all as he really didn't think it was necessary after all.   Well that made a first for a vet (and particularly this one who was always 'kerching').   She wasn't an 8 week puppy, but still quite young.

I hope you will reconsider buying this puppy - there WILL be others.   Having to confine such a young puppy while it recovers from surgery, any surgery really, could be very difficult!
