My name is Langston!

Langston is a mixed terrier breed but with the body and speed of a little greyhound. He is a lively 2 year old. He would not be suitable for apartment life unless adequate time for exercising and play time was given. I adopted him after he came to America from the streets of Mexico. He came with a mostly torn off left ear and a completely torn off or cut right ear. He is very friendly but can be hestitant towards men in the beginning. But always warms up to them. He is skittish in new environments and can be startled by sudden sounds.
I'm really hoping to find a home that has time and attention to give to him. He is house trained and knows basic commands. He loves to explore, to cuddle and is a very curious little guy. Weighs around 30 lbs and is a medium/slim build. Rehoming because of my schedule and he is not suitable for apartment living. since it's just him and I - I know it's not the best life or home for him due to being alone a lot.
