OMG, I am heartsick seeing that picture and can only imagine the heartache your friend is going through seeing her baby suffering from it. This little one and your friend are in my prayers for a full recovery from this horrific incident. I hope the groomer does right in paying any and all vet costs.
Kudos to you
for being there for your friend and coming here to find some info and/or reassurance for her...........and some good ol' YT prayers. I've seen them work wonders! Please keep us posted on her progress.
