Not sure this is exactly the right place to post this but did not really know where to post it, anyway here goes.
I have an old Pekingese (approx 13 years old) who I rescued about 5 years ago. Since Sunday night she has started barking all night long, it usually starts somewhere around midnight and ends about 7 am once we are finally up and getting ready for work. She sleeps in her own bed on the floor in the bedroom she goes out for final wee's about 10pm and then I put her in her bed, she is old and not very mobile as she has very bad but sadly inoperable luxating patella's. Nothing in here routine or life has changed in the last week? when it first started on Sunday night I tried ignoring her, when it did not stop I told her in a firm voice "Quite!", she still did not stop, I thought perhaps she needed to go the toilet I took her out a few times in the course of the night and she did nothing, or will do a wee but come straight back in and within 5 minutes start barking again. I try to ignore her as I donít want to reinforce the behaviour but it is just relentless "woof woof woof!" and I worry about the neighbours as late at night the sound travels. She has started getting out of her bed and wondering around the house barking at night, I have tried putting her on the bed and she still barks, she is quite during the day and does spend all day asleep although this is what she has done for the last 5 or so years I have had her. With her age and health she is not the sort of dog that you can take for a walk or really be active, and as we are at work all day she is home asleep all day.
This one really has me stumped I am about to call my vet and have a chat to her to see if she has any suggestions, but thought I would see if any of you guys had any thoughts or suggestions, the only thing I am thinking is some sort of dementia, although it has come on very suddenly. Like I said she is eating, drinking, going to the toilet and acting normal in every other way except the all night barking.
Any thoughts would be appreciated I have not had more than 2 hours sleep in the last 4 nights and am at my wits end with her.
