My guy is a Border Collie/Golden Retriever mix. I am wondering what breed he takes after in your guys opinions. He is 50 pounds and has a medium long coat that is all black. He has almost NO undercoat what-so-ever. He sheds lightly and a furminator doesn't work on his coat. If I brush him for half an hour I get maaybe a handful off of him. He is high energy but has no issues calming down. He needs half an hour of aerobic exercise a day to not be a crazy mess. He is *intense* about fetch and frisbee. He picks up commands within the first lesson. He chains commands together really well. He is friendly with people, but is almost shy at first. He just sits still and lets people pet him and will wag his tail and lick them. I love my guy and have been told by breeders and owners of both that he reminds them of their breed LOL. What do you guys think he sounds like?
