Honestly, I think you have a rare case of polar-bearitis.
There is also a possibility of permanent damage to the bladder or urethra. The urethra may become scarred, causing a permanent narrowing, or stricture.
The stain could be caused by mold. The wood should be pressure washed and treated with a sealer. Another type of black stain in timber is caused by iron oxide. When the moisture in the timber has caused the iron in any fixings, such as nails, to rust and form ferric oxide. This is black, and this travels through the moisture in the timber causing patches of black staining.
Chipping of the paint???^~^
It could, if it's leaking.
This could be areas of hardening or calcification around the urethra, the tube that you pee out of.
No. It simply doesn't work that way.
It could be your period or an infection if you are female. If you are a guy, it could an injury or infection to your urethra.
i think it might mean he/she is a little afraid of you. i have 2 jackson chameleons and my girl one is black. i just got her so she could be frightened causing her to turn black.
If the smoke is black it could be caused by a faulty fuel pressure regulator which could be causing the engine to get too much fuel.
It may be. It could also just be the metal in the ring turning black and staining your skin. My advice, take that ring out and put in a gold or sterling silver ring!
No. Just look at your own urethra how small that opening is. Women's urethral opening is smaller than mens. There is no way a penis could go in there and even if it could it should not be done because the environment is sterile.
This is called, tear-staining. If they are rubbing at their eyes a lot, you should book an appointment with your vet. This could be the start of a chronic eye problem. However, tear staining on white dogs is common and shouldn't be too big of a worry. Still, better safe than sorry and you may want to do some research on your own while making that appointment.
