Hey, sorry to bump up an old thread but I google searched for degu
hair loss and found this thread
We moved our degus (Pedro the introvert and cheeky Costas) to a six foot tall aviary about a year ago... they started to lose hair on their tails soon afterwards. As they didn't look sore or anything, we left them to it. They are both the offspring of a neglected parent whose owner was going to feed her to a snake before she was rescued! As such, one of them (the extrovert!) has a cataract... but he seems happy enough and his brother looks after him well. It certainly doesn't stop him chewing on the highest of the cage bars at 3am
Anyway, I noticed yesterday that the hair on their tails seemed to be slowly growing back. I haven't changed their diet at all (
chinchilla pellets and hay) and they have received regular sand baths throughout this period. As experienced rodent owners, we've never grabbed them by their tails and we've had them for three years, since they were old enough to be weaned. The hair loss was a bit of a mystery, but the regrowth is just as strange!
So all I would say, is unless it seems to be causing your degu any distress, I wouldn't rush her to the vets unnecessarily.
One day, your degu may grow back her lovely bushy tail
