teeth are a funny thing in a dog , they can be black as the night sky due to bad diet , and the dog may only be 12 months old , or a dog with pure white teeth and the dog be 5 years old , with good diet , teeth been white dont always mean the dog is young , or black teeth dont always mean a dogs old ,
but regardless this dog looks a cracking , and deserves a good home , regardless of his age , but as with any dog for sale , all you have to go on is the owners word , and if he / she hasnt had the dog from a little pup and seen the parents , then all he had was the owners word also ,
