Hardwood floors have no "give" to them, so there is no cushioning for her when she walks or jumps.
Maybe you should start giving her a glucosamine complex. That stuff can really do wonders for yorkies...humans too. I give Libby Flexicose which is a liquid complex and I get it on Ebay. Libby has LP and used to limp quite a bit and since having her on Flexicose, she doesn't show any signs of any problems. |
