This puppy is 3 months old, intact, with two sets of vaccinations. Seems to be fine with humans. I have him crate training with working k-9's in the room. Have not allowed interactions. No obvious issues. He is young. One of my clients surrendered when they realized the long term needs of the breed. Looking for a home that understands the demands of the breed. Sold to my client as a purebred but no guarantees.
