I'd believe low content is possible looking at the parents. The only way to be sure is to have their DNA run through the UC Davis Wolfdog hybrid test, or (possibly less accurate) Embark. Those are the only two places I know of testing for wolf content with any kind of reliability.
If you've been looking for a while you probably already know, but just in case: make sure you know your local laws regarding wolfdog ownership and follow them to the letter. People have had their animals seized before because they registered them as a domestic dog with the city, but posted about owning a wolfdog online or talked about it publicly. Make sure you have talked to your local vets and have found one who will work with a wolfdog - not all will. Know that even though the rabies vaccine is likely just as effective in wolfdogs as it is in dogs, it's not legally tested on wolves or wolfdog hybrids, and so the law WILL treat your dog like an unvaccinated animal if there's a bite incident. This may include euthanizing them to test for rabies.
Not trying to scare you, just emphasizing to anyone thinking about wolfdog ownership that there's definitely extra challenges beyond the animal's size and temperament they need to think about. Even with low contents.
