At first glance, this Border Terrier puzzle seems to show only the larger dogs arranged across the picture.
But several much smaller terriers are tucked behind, beside, and between them.
The easiest way to solve it is to scan the image row by row and count every individual dog, including the tiny ones whose bodies are partly hidden.
There are 10 larger Border Terriers that are easy to spot, plus 7 smaller hidden dogs scattered throughout the picture.
Answer: There are 17 Border Terriers in total.
