Here are several areas on pet, show, and meat rabbits where fur is commonly lost, and the causes and cures. A rabbit with bare spot can still be shown in most breeds. It is only a disqualification from competition in the Dutch breed.
Missing Fur On Ears
Some rabbits just genetically have poorly furred ears. Others go through stages when the ears are not well-furred. If your rabbit normally has well furred ears and is missing some, check for these signs of problems:
1. head-shaking and scratching ears [editor's note: indicates fur mites or ear mites/canker. Hair loss is due to rabbit scratching itself. May also cause wounds or bloody spots from the toenails scratching the ear. Ear canker is treatable with ivermectin. See our article for information. Fur mites like the ears because the fur is thinner there. I have successfully treated fur mites by spreading a thin layer of petroleum jelly over the ears once every day. The Vaseline smothers the mites. Really, it works!]
2. dander, also indicating fur mites
3. brown crustiness in the ear, indicating ear mites or fur mites.
4. a neighbor that licks his lips every time that ear gets near the cage wall
If the problem is not due to parasites, try to breed this rabbit with one that has better fur covering on the ears if the problem is pronounced.
Missing Fur Under The Chin In Dwarf Rabbits or Any Other Breed
Fur may be missing for one of these reasons:
1. excessive chinning
2. abscess of the scent glands
3. moist dermatitis (especially in does with excessive dewlaps)
5. rough feeders
Abscesses often need to be lanced and/or treated with antibiotics (check with your vet).
For moist dermatitis, I would use a water bottle placed higher than usual and place a purple wound powder, made for horses, on the affected area.
Check out your feeders for sharp or rough edges. Plastic feeders, too, can start ripping out fur once the rabbit has chewed the edge into a rough pattern.
Loss of Fur in Other Areas
Hair Loss over the Shoulders
Although fur missing over the shoulders could be barbering by a neighbor or the start of a molt, chances are that if you blow into the poorly furred area, you will see dander, the telltale sign of fur mites.
Authorities seem to disagree about how to treat fur mites. I use ivermectin and it works for me.
Stripe of Fur Lost Down The Back
Occasionally I’ll have a rabbit look as though I took a razor and removed a strip of fur from neck to tail. Sometimes it is down the middle. Sometimes it is to one side. As bizzare as it looks, it’s just the start of a rabbit shedding. I love this sort of molt because, in my experience, the molt goes very fast. It’s also amusing to watch.
Missing Fur on a Bunny’s Face, Between the Eyes
Blame the neighbors for this one. The missing fur is most likely caused by barbering. You can add a layer of hardware cloth to the cage wall to keep teeth on the correct side of the cage wall.
Missing Fur On Footpads
Missing fur on paws is just one step away from sore hocks, in my opinion. It amazes me how many rabbits have worn fur on their feet that come across the show table, especially rex furred breeds. Keep an eye on those feet and treat for missing fur so that you don’t have to treat for sore hocks. You can improvise a resting board from wood or other smooth surfaces. Or you can purchase pre-made resting pads that allow waste to drop through.
When you think about all of the things that can happen to fur in addition to normal molting, it can really make one appreciate a great fur even more.
