Random dog PSA:
My inlaws got a rescue mutt about 6-8 months ago. Super sporty, health 50-60lb pup that's about 1.5 years old. She was running around in the back yard chasing a rabbit when she went limb. Back half completely paralyzed. After spending thousands of dollars on MRI's and stuff at the vet, turns out it was a spinal stroke, and she should mostly make a full recovery after a few weeks. Never realized such a thing could happen, but its pretty scary. I think my takeaway would be that if it happens to my dog, I'm not spending the money because it is either temporary and will get better on its own, or permanent, and there's nothing you can do, so throwing thousands of dollars at a vet isn't going to change anything.
