My wife and I adopted a former stray, 2yo Golden Retriever mix. Most of the day, he's pretty lazy and not active and we are trying to potty train him.
Our problem is that this dog has not given us any signs that he needs to pee. He usually sits in one location and naps. But sometimes he will go and explore the house. Usually, this is when we stir around the house, but not always.
To be clear, when he's gone 6-8 hours without peeing, we go in "hawk" mode where we watch him like a hawk. This is because like lightening, he'll get up, go to the nearest carpet and start peeing. No signs, often no sniffing or circling--he just pees where he wants.
To make matters worse, we take him out every 2 hours during the day. My wife and I both work from home, so we can dedicate a lot of attention to him. He will poop outside, but he has peed outside only once. We don't play with him outside so we don't distract him and we try to pull him in the direction of quieter areas of our yard so he has a single-space to go. Regardless, he's a very attentive dog and if a car honks a horn on the other side of the neighborhood or a squirrel makes a noise in a tree, he turns his head towards it. He doesn't seem afraid, just very attentive. However, when the yard doesn't distract him, he plops down and will just lay there. Often the whole time, because he prefers to be outside (which is ironic since he won't pee out there.)
Furthermore, on multiple occasions we've taken the dog out for 15-20 minutes doing nothing with him other than letting him stroll around the yard and within 5 minutes of getting him in, he runs to some carpet and starts peeing. There have even been occasions where we've taken his harness off, and before removing our jackets, he's ran to a spot (again, no sniffing or circling) and pees!
We have read multiple articles and questions on the internet, but my dog seems to be very determined to stay inside and pee, even inside his crate. We've resorted that if he goes for a long period without peeing, we keep put a leash on him and keep him in our hands. Regardless, he's stubborn and hates the leash (his crate too) and we have to use both of those items.
Sorry for the long story, but nothing we've found has helped. What else can we do for this dog and our house?
