Max is a Yorkshire Terrier like the one just under the Toy Group name. Chula is a Chihuahua but she is very light, not like the one in the upper left side of the quilt.
The Working Group has another bunch of wonderful dogs.
This is the Herding Group. I used to have an Old English Sheepdog named Max - all my dogs are name Max, except Chula who is named after a Chihuahua I had as a child.
Here is the Hound Group.
