We have a 9 week old American Cocker Spaniel (chocolate Merle parti). When we were waiting for our boy to come home, his breeder sent me pics of his sister who looks just like him from the previous litter. When she first showed me pictures I thought it was a completely different dog. I couldn’t believe how much her puppy coat changed as she got older. She went from a chocolate Merle parti to more of a silver/blue. Has anyone ever seen these color changes? I’d like to upload some pictures but I clicked attachments but there’s no option to add pictures.
