He’s ugly?!?!?

I am puppy sitting my neighbors new puppy for a couple days. They wanted me to leave him on a tiny porch for hours a day and just take him for a walk and feed him in the mornings. I decided that I couldn’t do that. So after his walk I bring him over to my big fenced yard and attach him to my dogs lead so he doesn’t get away from me. He is a Collie and Pit bull cross. He is nothing but energy. He is proving hard to train because he doesn’t want to learn to calm down enough to learn a trick, but he’s a puppy. After his walk we come to my yard and play fetch for at least 2 hours and he still wants to go, go, go! After playing I do take him back to his porch though. I clean up his poop, and give him fresh water. I texted my dad to show him how cute this puppy is and my dad says he is ugly because he is a “mutt”. I think he is ADORABLE!!! My mom also thinks he is ugly! Like, how do you look at that face and say “he’s ugly”?!?!?
