I’m looking for a rescue pit bull that I am able to compete in agility with and possibly other sports in the future. I found a sweet young girl who loves other dogs, cats, and has boundless energy- but she has had surgery in the past to repair a torn knee ligament. My question is would this be something that could cause problems in the future as far as being able to compete in dog athletics? I’m looking for a serious competitor dog- not just a fun agility partner. Thanks!!
