Are my Mastiff Lab mix dogs also Pitbull? How can I find out?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Large (61lb +) | Male | neutered | 1 year and 1 month old | 100 lbs

I really would like to know what my dogs (siblings) are mixed with I know for sure English mastiff and Labrador but I want to know what the third breed would be. I'm thinking a pitbulls because the red nose and big heads but I don't know for sure.

You could be absolutely right about the third breed. They are cute dogs for sure! If you want to know for sure, you could send out a DNA panel such as the wisdom panel. It is pretty cheap to send out.
