Customer Question

I wondering if someone could look at the for on my 4yr old boxer. It seems that she is getting bald spot. I used a non shedding shampoo that seemed to help
JA: I'm sorry to hear that. Using the wrong medication for fleas can be dangerous. You should definitely talk to the Veterinarian. What is the boxer's name and age?
Customer: No flea medication. She is 4 And her name is anja (soft j)
JA: Is there anything else the Veterinarian should be aware of about anja?
Customer: Hmm she is healthy. She and her older sister are kept indoors during the day whole we are at work. We try to let them outside to get some sun

Thank you. Give me a moment to take a look, please...

The photos suggest pattern alopecia (seasonal flank alopecia, cyclic flank alopecia, cyclic follicular dysplasia) common in bulldogs, boxers, airedales and schnauzers. The exact cause isn't known but photoperiod control of melatonin and prolactin secretion may be involved. The onset of alopecia in the northern hemisphere usually occurs between November and March. Most dogs regrow their hair spontaneously 3-8 months later. Episodes of hair loss may occur sporadically only once or twice, or regularly each year. With repeated episodes, a progressive increase in the amount and duration of hair loss may be seen.

Observation without treatment is reasonable because this disease is purely cosmetic and affected dogs are otherwise healthy. Treatment with melatonin may be effective. Protocols include melatonin at 3-12 mg/dog every 12-24 hours for 3 months and several weeks before the onset of the next expected occurrence. The prognosis for hair regrowth is variable. Regrowth may be incomplete and new hairs may be duller in color and drier in texture.

Please respond with further questions or concerns if you wish.

You're welcome. Give it a try. Melatonin is safe and completely nontoxic in dogs. Please continue our conversation if you wish.
