My 11yr. old Jack Russell has just been diagnosed with a tear in her AC Ligament, also possible meniscus tear. My problem is with her age 11 am I being foolish putting her through this? She has a mild heart murmer, is 7-8 lb. overweight(we're working on it) She is not very active since a scarey bout with pancreatitis in December of which she seems completely recovered.All I have read tells me the other elbow(ACL) has a 50% chance of going within a year, not sure I'm being objective. HELP advise needed.
