May I ask, do you know for sure that your Pyr is the father? How do you know, and of which pups?
It looks to me like that lab got in there.
It is common for litters to have multiple fathers if the female is available to them.
I ask because my wife and I are moving onto our beautiful 40 acres soon to start our permaculture dreams outside of St. Helens, OR,
and we are definitely looking to give one or more pure bred Pyr's a loving and working home.
They are so cute, congrats!
