I like mixed breed also. They are not so inbred that they have so many physical problems.
I found my Fred running on the street, spray painted with green stripes down his back.
He was so hyper I was sorry I picked him up.
Took him to training classes and had him neutered.
Vet says he was about 10 months old.
So his birthday is the 4th of July. We have a big party with fireworks. Maybe you have heard them.;-)
Fred is the best dog we have ever had.
