I dogsit sometimes and just took on a new client yesterday. She's a mostly sweet two-year-old poodle, except for the peeing (and sometimes pooping) inside thing.
I've now walked her three times:
First time: 45 minute walk about 4 hours after she was dropped off, she doesn't pee or poo (she had already pooped inside right after arriving.) Get inside and she has dinner then wants to play, then while playing squats down and just starts peeing... while jumping around. Ok, maybe put that one down to over-excitement... if it hadn't kept happening.
Second time: Another 45 minute walk, she does poo late into the walk and then I stand with her in my back-yard for an extra 10 minutes waiting for her to pee. Get back inside, she goes to her dog bed and lays down... then as I'm watching she gets up and squats down to pee in/around her bed.
Third time: Just walked her for over an hour, no pee or poo... so tied her up in the back-yard and stood there waiting over half an hour for her to go. Still nothing... right now I've just got her "locked" in the kitchen since the linoleum is a little easier to clean.
I just don't understand this though, every other dog I've ever owned/watched pees immediately when going outside... especially in the morning! It doesn't seem like a medical issue... she's not having trouble controlling her bladder. She goes hours just fine, and even asks to go out when one might expect it's time for her to potty. No accidents overnight even. It's just that when we walk, she seems to think she should potty inside after the walk...
Any ideas why a dog would act like this? Or how to correct her behavior?
