Hello, I recently adopted a 8-10 week old puppy from the local shelter and we are trying to figure out what type of breed mix he is. From the picture you can see that he has floppier ears and he also has a very thin tail. The shelter listed him as a pomeranian mix, but I doubt that. At 10 weeks he is about 11lbs. He has fairly long legs with a furry puppy coat. Through all the internet searching I think that he may be a golden retriever/Border collie mix, but i'm not sure where he is getting the Brindle coloring. Also, he has been getting noticeably lighter each day and the black is starting to slowly wear away into a true brindle coloring. Any suggestions or help would be great.
