If you see your active dog suddenly start limping or doing the "bunny hop" it may be due to a torn ligament. You may also see them holding up a paw, lameness or sitting abnormally. ACL tears can be tricky to detect where the dog is limping temporarily and then later appears to be walking fine.
Not all ACL tears require surgery. You may be able to use a conservative approach which includes rest and natural remedies to help reduce inflammation and repair connective tissue. Ask Ariel's Ultra-Flex Collagen is a whole-food supplement that builds cartilage, joint and connective tissue. If ACL surgery is necessary, Ultra-Flex Collagen natural can also aid in recovery.
