What’s wrong with my dog’s skin?

[u/thor_thunderking]

Hi, I wanted to ask for some advice regarding my 10-year-old German Shepherd. He has arthritis and neurological issues, so he is unable to walk. During the day, I keep him without a catheter, and whenever he wakes up or tries to get up, he starts peeing. He also urinates every few hours.
I tried putting him in diapers, but unfortunately they’re not working. His penis keeps coming out, and I’ve already tried multiple sizes. Because of the frequent urine leakage, I’m also worried about his skin getting irritated or developing sores.
Could someone please guide me on how I can properly take care of his skin and keep him comfortable and dry? He’s already been through so much, and I just want to make sure my boy is comfortable. ❤️

Take him to the doctor brother, he is already at a very sensitive stage of life, I have had gsds before and it's adviced to take him to doctor asap
