I was a vet tech, not a vet, so I'd advise a vet appointment to check this out. It could be Luxating Patella. Toy dogs are prone to having this, especially Yorkies. These's 4 grades. Grade 1 is when the knee pops in & out on it's own. The dog can live with this & not have any problem. Grade 2 requires manual manipulation to re-seat the knee. Grade 3 is the same as Grade 2, except the re-seating is only temporary. Grade 4 is worse, the knee dislocates, pops out, painful for the dog and surgery is recommended. |
