It would make a friend’s year if I could find this…
Kid’s book. White cover. Most likely from the 60’s or 70’s. Maybe 50’s.
Child and dog growing up together. At end of book dog is huge and doesn’t fit on rug that is throughout the book. Almost written as a dog care guide. Kid gets the puppy, feeds and takes care of puppy as they grow together. Sketch style artwork. Subdued colors. Irish settler like dog. Probably 8″ x 11″ book. Maybe 20 pages.
Could this be Five Beds for Bitsy by Ian Munn? I had this book as a child and loved it!
