Hi and welcome to Binkybunny!

If buddy’s toe broke or got dislocated months ago, and he still seems fine, albeit with a weird toe, I dont think a vet would do very much. They could x-ray his foot to assess the damage, but I doubt they’d do anything about it. This is if everything looks ok, no swelling, discoloration, seepage, etc. Is he moving around like normal? Is it a back toe or a front paw toe?

The site hocks-issue is more serious imo. Buns dont have padded paws, they only have fur and skin over the bone. If the fur wears off, the bun can develop calluses on its heels. Calluses offer some protection, but needs to be kept a close eye on. You can use for example nappy rash cream on the bare patches so the skin doesnt get scaly and brittle. It is very important to check daily, because if sores develop, you need to clean the sore and put on antibiotic ointment (triple antibiotic ointment or fucidine) right away and make a bandage like in this article:

In order to make such a bandage you need some bunny fur. I suggest you start saving all fur you brush off of your buns when you brush them, because it’s good to have a small stash of bunny fluff in case you need it later on. I have used the bandage in the article I linked to, with very good result.

If you think Bella’s hocks are inflamed, you should see a vet. It’s great that you have been saving up for vet costs!

If you think it’s just normal callusing, and the fact that she still has some hair on her hocks speaks in that direction, you can just keep an eye for now and put on cream, sudocream or mild nappy rash cream. Those creams contain zinc and zinc is good for skin healing. They’re not toxic if your bun ingests some. Check the feet every day and apply cream. Also keep her nails short, long nails can cause the bun to put more weight on her heels than she’d do with shorter nails.

Also keep an eye on Buddy’s hind feet. A crooked toe or some other injury, even long after it has healed, can cause a bun to put its weight slightly wrong on the feet, thereby increasing the risk of sore hocks.

As for nail clipping, I always ask for help from another person. The other person holds the bun in their lap, the bun with it’s back towards the person’s tummy, much like if the bun was sitting in a chair. A tiny treat, like a sunflower seed, between each clipped nail can sometimes work if your bun is very interested in food. Some buns refuse treats if they’re stressed though.
