Colourful bears?

So I’m not too sure how this works by basically there was a book I loved as a child that I am looking for online as I remember living it, it may not be lost but I can not find it, a description from my memory of this book was it was of colourful bears or maybe just animal style walking on two feet but they were all different colours yellow etc. In the book I’m pretty sure that they finding a missing dog I know this isn’t much to go off and that’s probably why I ant find it. I also remember that one wore glasses and was green I think. I will continue to look for I think and would appreciate all the help I can get plz contact me if u fing it or any info
