Barx buddy Notice the movement of your pet, whether he is swift in his movement or taking a time to get up or jumping. Whether he is limping or reluctant to walk. This can direct you that whether he has got some injury in his leg or may be facing a problem of arthritis. At the notice of any unwanted signs on your pet's body, consult your vet for further diagnosis or treatments. This greatly lowers the vet bills due to treatment of diseases in advance stages. Keep Your Pet Moving.
