Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. If Coco has been losing weight, I would recommend having her blood tested and having her thyroid level checked to see if the weight loss and fur loss are the cause of a hyperthyroid. I hope this helps guide you in the right direction. Please let me know if you have any other questions or concerns and I would be more than happy to help you further.
