BS!
We had a half wolf bitch that was the best family dog anyone could ask for. Wolves have strong pack instincts which makes them very protective of the family, but females are not typically aggressive without provocation.
My parents had a rescue dog that looked like a small German Shepherd. My mother fed,bathed and brushed it back to health.
Then took it to the Navy Veterinarian; my dad was career Navy.
The vet took one look and said ‘half wolf, you can’t bring it in here’! After a bit of stand off he agreed to see his new patient.
That wolf dog(?) and my parents spent many,many good years together.
