Mine had this done nearly 4 yrs ago and has been absolutely fine and in fact competes at a higher level than she did pre op. Not sure if I would buy one with this having been done but it is now an almost routine procedure and many have had the op. Acc. to my vet as the incisions are so small it could be hard to detect at a vetting. Plus side they are being upfront and you should get a good price as a result.
