All bunnies seem to shed a little differently based on the bunny and based on the breed also- rex or mini rex rabbits often look as though they get “clumps” that are ready to come out.  I don’t see those too often on my lop breeds.  My Mini Lops seem to shed all over- no noticeable clumps.  My English Lop has shorter fur (at least at this age- 4 1/2 months old) and I can see a noticeable shed pattern on his back where the fur looks shorter as he sheds it out and regrows his fur.

Some bunnies- like shaded bunnies- Siamese (called sable) or color point bunnies- you can notice a color change as they shed- they typically get darker as they get older- and mid-shed you can see the darker fur coming in.

Edit- if you dampen your hands and then pet your bunny it will grab out the loose hair- then rub your hands together to clump the fur up to be able to throw it away- it helps getting not quite as much fur in the house!
