I'm pretty sure this has been discussed before but I couldn't find an answer for an adult dog. My wife & I are fighting over how often the dog (2yo Brittney) needs to go out. She insists he go out right at bedtime but if I do this then I have a hard time getting to sleep after. So I walk him about 9pm and she does it in the morning about 8am. Is this too long? He has not had any accidents in the house. Typically he doesn't bother to get up & come downstairs when I get up to go to work so it seems he's not urgent to go relieve himself.
If heís not having accidents in the house whatís the wife worried about? My worry would come when pee and poo are everywhere. I personally donít think there is a right or wrong answer here. It is the ownerís decision on when they take the dog out.
I will tell you what I do and that is let my shih tzuís out around bedtime so 9 p.m. - 10 p.m. and they do not go back out again until 8 a.m. Shih tzuís have smaller bladders than a Brittney does, and mine are just fine all night long. I sure hope this helps. Take care and good luck with the wife.
