So…
The vet said good news is the dog has an infected paw.
The bad news is the dog is a “Car crash dog, not metaphorically speaking!” as in the poor thing was probably hit by a car, once.
Numerous old untreated injuries and probably wouldn’t find a forever home.
He was owned once, and castrated, probably about 5 years old, but who knows, covered in fleas, filth, scars and all sorts.
They can treat the infection and clean him up and de-flea him.
Oh heck! I guess I own a dog now.
