These days we all hear about “core strength.” As humans we tend to think of it as “abs.” More realistically “core” is just that – it is the core workings of the body — the part that makes all the other parts work together. If your dog has an injured limb and no core strength, he’s stressing his back to make adjustments for limping as he heals. If your pet has a back injury, without core, she is sagging in the middle and likely to injure again. If your fly ball dog (or your frisbee maniac) has poor core strength but is fast, when he starts to slip on a fast turn, he either will fall, or is more prone to injury
