This book I read in the 90's and back then it looked old to me, maybe from the 70's or 80's. It was in black and white, and about dogs. The book was similar to I Spy, you had to search for items in the pictures, but wasn't I Spy. The pictures themselves were hand drawn. Any help is appreciated, thanks!

Is it this?

Amazon.com: Harry the Dirty Dog (9780060268657): Gene Zion, Margaret Bloy Graham: Books (http://www.amazon.com/Harry-Dirty-Dog-Gene-Zion/dp/0060268654) (1956)

It has been reissued and colorized.

No, it was like an I Spy book, not much of a story, and had lots of dogs, not just one. Thanks for your answer!
