I have a 3 year old, female Bishon Fries. She has developed bald spots on her back side upper thigh and back by the tail area. She is not scratching or licking. One balding patch has on the skin has a tiny red raised pimple. The back has a tiny white pimple. No change in behaviour, eating, drinking as normal. Any ideas ?

A common mite called demodex will often cause hair loss without itching. Also, Skin infection caused by bacteria or a fungal infection such as ring worm is also possible. She is a little young for hypothyroidism, but it is still possible. I would highly encourage you to have her evaluated by your veterinarian soon. They may do a skin scraping to look for mites and may recommend blood work to check her thyroid level. Best of luck and thank you for using Pet Coach.
