PM update - I was able to handle her paw, trimmed away fur, and cleaned it - looks raw & granulated, but not a puncture. we bandaged her paw, but when she walked on it she bled like crazy - really scared us. So i took it all off and have been keeping her inside and quiet. (not easy as my new "husky granpup" visited today- what a cutie!)
She's stilll bleeding when she puts pressure on it, but I'm afraid to bandage it again. We'll definitly be at the vet's Monday morning! Will order boots on Monday, too. Please keep paws crossed she's ok.
