That dog by Nanette Newman

That dog! by Nanette Newman, illustrated by Flora Daneman. Brubaker, Ford & Friends, 2011. 

Barney is That Dog!, as called by the neighbour. But he is Ben’s best friend – part of life since Ben’s birth. Ben is broken hearted, but his grief is helped by the discovery of a lost puppy. 
Soft and gentle illustrations accompany the gentle text. However, it does seem that Ben’s recovery is unnaturally swift.
