My dog is old and has started needing repeat trips outside at night as if he needs the toilet, but doesn't go.

He's 14 and is a poodle cross so I'm sure it's an end of life thing, just wondering if there's anything I can do to help.

He'll have a night time walk and go to the toilet, but a couple of hours later once we're asleep will then get locked into a cycle of asking to go out multiple times.

In the day he can happily sit and sleep for hours without needing to go, but at night it's become impossible to stop.

He's not desperate, sometimes he'll go out, have a walk about, then come back again and not need a wee. But then 5 mins later need to repeat.

I'm not sure why this only happens at night. Not sure if there's anything I can do to help. If it's likely time to have "the chat" with the vets it will be heartbreaking, but I'd rather know and ready my family for it than see him confused like this every night.

Any advice would be much appreciated.
