I had the same issue with Daisy! The vet told me her ligaments were loose, Daisy didnt have the clicking sound but she was limping a lot...she too thinks she's a bird! I began to give her Dasuquin after a possible surgery needed scare and she's been doing great! I would have to have to have her go through surgery, but so far so good...I now give it to both my Morkies and they like it...its Pricey but you can split the tab.
