I would love to know what breeds my dog is made up of. I have a mongrel called Tarka. He's mainly black, with gingery-tan on his face, eyebrows, legs and the underside of his tail. He has a white belly and chest and long hair. He's medium-sized, very sensitive, very intelligent, hates to be left alone and has tons of energy depsite being 11 years old. He loves to be stroked and loves playing with his toys. He's very social with everyone, growls at no person or dog. He's called Tarka because he hates getting wet, it's an ironic name which comes from 'Tarka' the otter!
Here's 2 photos, please help I really want to know!

Thanks in advance!
