i sold my pup last year because i didn't have the time due to work an i got offered him back on Christmas eve so jumped at the chance at getting him back but when he got here i noticed that he had 2 bald patches on his back legs and his elbows were bald aswell . 
  
 i asked the boy i had sold him to what had happened to him an he said the boy he gave him to had put him in a kennel with no bedding , i thought that the hair would have started growing back now hes in the house but its not . 
  
 i was just wondering if it will grow back and if i could do anything to help it ??  
  
cheers tony !
