Very basically skin consists of three layers. The epidermis (the top), the dermis (next layer) and the subcutaneous layer. I found a page for you to read about it if you have forgotton what you learnt in school.
When Wai came he could not wag his tail because it was encased in the brown hard sharp saddle leather that is his skin now. Somehow and at some cost – he must have rubbed his rear hard on a wall or something – he managed to release his tail so he could wag it. (now he has a hole going in below the upper layer of damaged skin, straight in under the dermis and exposing the subcutaneous tissue).
And even though the poor fellow is all nerve endings and pulling and rubbing from hard outer skin curling like hangnails into his skin, and exposed insides, he still wags his tail when he sees his pumpkin. I don’t know how he is carrying on, unbelievable really. Hats off to this fellow.
This hole is why I cover him with a sheet when he lies down. It is deep and also goes right up under that layer of armor. There are other areas where the sharp edges of the armor have worn through into the fat layers but this is by far the worst. I cannot cut this away yet as it is still attached to the dermis. Very attached. It will be a while. My tree hospital. On the far left is the damaged walnut bolted together and tied with ties and on the right the new oak, planted and soaked and being held up using T posts and an old hose.
Lots of water and tree talk. Poppy is a nice pig when she is not in heat.
I hope you have a lovely day.
I don’t know what the weather is for tomorrow. But today was sunny and still. Lovely.
